Ask to Buy vs. Mst: Wishlist + Marketing Flow

Introduction

Choosing the right set of tools for a Shopify store can feel overwhelming. Many merchants face a familiar trade-off: add a single-purpose app that solves one problem well, or invest in a broader platform that covers multiple retention needs. This comparison focuses on two popular single-function apps in the wishlist/cart-sharing space and helps merchants decide which fits their immediate goals.

Short answer: Ask to Buy create & share cart is a focused solution for letting shoppers create and share ready-to-pay carts — useful for gift registries, parent-approved purchases, and sales-rep workflows — while Mst: Wishlist + Marketing flow is a feature-rich wishlist product with alerts, multiple wishlist options, and extensive customization. For merchants who want fewer moving parts and integrated retention tools, a consolidated platform like Growave often delivers better value for money and higher long-term ROI.

Purpose of this post: provide an in-depth, feature-by-feature comparison of Ask to Buy create & share cart and Mst: Wishlist + Marketing flow so merchants can choose the tool that best fits their store needs. The analysis highlights strengths, weaknesses, implementation considerations, pricing realities, and practical use cases. After the comparative review, the article explains the trade-offs of app sprawl and presents a multi-tool alternative that reduces complexity.

Ask to Buy create & share cart vs. Mst: Wishlist + Marketing flow: At a Glance

Deep Dive Comparison

This section compares the two apps across relevant merchant decision criteria. Each subsection covers practical outcomes such as conversion, retention, operational friction, and cost.

Core features and how they affect conversion

Ask to Buy: focused cart-sharing mechanics

Ask to Buy specializes in creating shareable carts that land invitees directly at checkout with pre-filled customer and shipping details. That reduces friction for the payer because they only need to complete payment, which can materially increase conversion in scenarios like:

• Teen shoppers who want parents to complete payment.
• Gift registries or group gifting where one person pays on behalf of another.
• Sales reps creating carts for customers and sending a ready-to-pay link.

Operationally, the app supports built-in buttons and customizable triggers for creating shares. It also tracks cart shares, conversions, and revenue generated by shares — analytics that help merchants assess how effective cart-sharing is for conversion.

Key practical benefits:

• Removes form friction by pre-filling checkout data.
• Converts social or family intent into completed sales faster.
• Good for merchant workflows involving sales staff.

Limitations to keep in mind:

• Narrow scope: primarily focused on share-to-pay flows rather than wishlist management or long-term retention.
• If a merchant’s priority is capturing product interest over time (e.g., to re-market later), Ask to Buy delivers limited functionality.

Mst: Wishlist + Marketing flow: wishlist-first with alerts

Mst focuses on wishlist creation and ongoing engagement. Core features include unlimited items per wishlist, multiple wishlists per user, guest wishlist support, and price-drop/back-in-stock alerts through email, SMS, or push. Merchants can fully customize the wishlist UI and integrate via API or headless implementations.

Practical benefits:

• Captures intent: wishlists are a persistent signal of purchase intent, useful for retargeting and email flows.
• Notifications (price-drop/back-in-stock) close the loop by re-engaging customers when product conditions change.
• Multiple wishlist support gives shoppers a richer, organized experience.

Limitations:

• Less focus on immediate checkout friction like pre-filled carts; wishlists often require an extra step to convert.
• While the app supports marketing notifications, a merchant will still need a broader retention strategy (loyalty, referrals, reviews) to increase overall LTV.

Pricing and value for money

Pricing must be evaluated in terms of both monthly spend and the business outcome that spend enables.

Ask to Buy:

• Listed plan: Basic at $15/month.
• Value proposition: For stores that convert meaningfully via share-to-pay carts, $15/month is reasonable if cart shares turn into regular orders (especially higher-value transactions).
• Considerations: Because the app is single-purpose, merchants relying on multiple single-function apps could find their total monthly app bill increases quickly.

Mst: Wishlist + Marketing flow:

• Listed plan: $2/month (one fixed cost for all features).
• Value proposition: Extremely low entry cost with many wishlist features included, offering direct value for capturing intent and sending alerts.
• Considerations: Low price is attractive, but it covers only the wishlist and related alerts. Merchants that require loyalty, referrals, or reviews will still need additional apps.

How to evaluate value for money:

• Measure incremental conversions and average order value (AOV) directly attributable to the app (Ask to Buy tracks share revenue; Mst tracks wishlist behaviors and alert conversions).
• Compare total cost of ownership across the stack. Two cheap apps can add up to more than an integrated platform that delivers multiple retention functions.

Integrations and technical compatibility

Integrations matter for data flow, automation, and marketing orchestration.

Ask to Buy:

• Primary focus is cart-sharing and checkout pre-fill. Integration surface is lighter and oriented around checkout and basic tracking.
• Works under a wishlist category but has fewer published integrations to email or CRM tools.
• For stores that use advanced automations (Klaviyo, Shopify Flow), connecting share data to flows may require custom work.

Mst: Wishlist + Marketing flow:

• Lists integrations with Klaviyo, PushOwl, Brevo, and others. Supports API and headless theme setups.
• The app's marketing notifications can be connected to existing email/SMS systems to trigger price-drop or back-in-stock messages.
• For merchants who rely on multi-channel reactivation, Mst’s integration list is an operational advantage.

Integration outcomes:

• If the business already has a marketing stack (Klaviyo, SMS, push), Mst’s integrations enable easier automation of wishlist-driven flows.
• Ask to Buy is more transactional; connecting its events to a broader CRM requires additional engineering.

Implementation, UI and merchant experience

Ease of setup and theme fit

Ask to Buy:

• Setup focus on adding AskToBuy buttons and customizing welcome messages at checkout.
• Fewer UI elements to place means simpler theme changes for most stores.
• Good for merchants who want a single, limited touchpoint without reworking storefront templates.

Mst:

• Offers a fully customizable My Wishlist page using Liquid, HTML, and CSS — useful for stores that want the wishlist page to match their brand experience.
• Because of the customization options, some merchants will require developer time to achieve pixel-perfect integration.

Shopper experience

Ask to Buy:

• Invitee lands in checkout with pre-filled data; conversion experience is optimized for a quick payment.
• Ideal when the shopper’s intent is immediate but the payer is different.

Mst:

• Shopper can save multiple wishlists and receive alerts later; conversion is event-driven rather than immediate.
• Useful when shoppers are browsing and not ready to buy, but want to be notified when conditions change.

Analytics and reporting

Both apps provide some level of tracking, but the depth differs.

Ask to Buy:

• Tracks cart shares, conversions, and revenue generated by shares. That makes ROI measurement for the share-to-pay flow straightforward.
• Merchants who want to understand which sales reps or campaigns drive share conversions can get useful attribution.

Mst:

• Tracks wishlist add/remove and performance of price-drop/back-in-stock notifications when integrated with messaging channels.
• Offers data useful for segmentation: customers who add items to wishlist but never purchase, items with high wishlist rates, and re-engagement success.

Analytics outcomes:

• For near-term sales tied to shares, Ask to Buy’s conversion tracking delivers a clearer short-loop metric.
• For long-term intent capture and lifecycle analysis, Mst’s wishlist metrics feed segmentation strategies and retention optimization.

Performance, mobile behavior, and accessibility

Mobile optimization affects conversion because a growing proportion of traffic is mobile.

Ask to Buy:

• Because it funnels invitees straight to checkout, the mobile experience matters at checkout level — a pre-filled checkout reduces typing on mobile and can improve completion rates.

Mst:

• The app emphasizes responsive design. Well-implemented wishlists that work seamlessly across desktop and mobile increase the chance shoppers will save items rather than abandon.

Accessibility considerations:

• Both apps require merchants to test across devices and ensure custom buttons or wishlist pages meet accessibility standards. Mst’s customization power helps but also raises the risk of introducing accessibility regressions without adequate testing.

Data privacy and compliance

Merchants must be mindful of consent, especially for notifications via email, SMS, or push.

Ask to Buy:

• Sharing carts and pre-filling payer details involves storing and transmitting customer information. Merchants should confirm the app’s handling of PII and ensure consent workflows align with legal requirements.

Mst:

• Sends price-drop/back-in-stock alerts via multiple channels. Merchants must verify subscription consent flows and data retention policies to remain GDPR- and TCPA-compliant.

Practical steps for merchants:

• Verify the app’s privacy policy and data processing addendum.
• Configure consent capture on signup or wishlist save to avoid violating opt-in rules for messages.

Support and credibility

Ask to Buy:

• Small number of reviews (7) with a 4.4 rating suggests the app is fairly new or niche. A modest review pool makes it harder to generalize about support responsiveness.
• Merchants should trial the app and test support responsiveness before relying on it for critical workflows.

Mst:

• Larger review base (150) and a higher rating (4.7) indicate broader adoption and more consistent positive experiences from merchants.
• The volume of reviews can be a proxy for maturity and reliability, though merchants should still test support in their own use case.

Scalability and when the tool becomes limiting

Ask to Buy:

• Works well at low-to-moderate scale where cart sharing is an occasional but high-value use case.
• At scale, merchants may need more robust wishlist, loyalty, or referral solutions to increase repeat business — areas outside Ask to Buy’s scope.

Mst:

• Scales well as a wishlist solution because of headless support and API access.
• Still focused on one part of customer lifecycle; merchants aiming to increase lifetime value will need complementary tools.

Practical use cases and merchant profiles — which app suits which needs

Ask to Buy is best for merchants who:

• Rely on share-to-pay scenarios (teens, parents, registries).
• Have sales reps who create carts for clients.
• Want immediate conversion through a frictionless checkout experience.
• Prefer a small number of UI changes rather than a broad site overhaul.

Mst is best for merchants who:

• Want to capture long-term purchase intent and re-engage customers via alerts.
• Need robust wishlist management, including guest users and multiple lists per account.
• Require integrations with email and push vendors to automate reactivation.
• Seek a low-cost entry point to track wishlist-driven behavior.

Pros and cons — concise merchant-focused summaries

Ask to Buy — Pros:

• Optimizes checkout friction for shared payments.
• Tracks share-to-purchase attribution.
• Reasonable priced for single-purpose use.

Ask to Buy — Cons:

• Narrow feature set; limited for broader retention strategies.
• Small review base — less publicly available social proof.
• May require other apps for wishlist, loyalty, or review collection.

Mst — Pros:

• Rich wishlist features at a very low monthly cost.
• Strong integrations for notifications and headless support.
• Larger review base with higher rating suggesting maturity.

Mst — Cons:

• Not focused on checkout friction or share-to-pay mechanics.
• Wishlist data is valuable but typically needs additional retention programs to maximize LTV.
• Customization can require developer resources.

The Alternative: Solving App Fatigue with an All-in-One Platform

Single-purpose apps like Ask to Buy and Mst solve specific problems well. But as stores add apps for wishlists, loyalty, reviews, referrals, and more, technical debt and monthly costs accumulate. The result is "app fatigue": too many integrations, redundant data flows, inconsistent customer experiences, and rising support overhead.

Why app fatigue hurts growth

• Fragmented data: Customer intent, purchase history, and loyalty actions live in separate apps, making coherent segmentation and personalization harder.
• Performance and theme conflicts: Multiple apps that inject scripts and UI elements increase the risk of slow pages and front-end conflicts.
• Operational overhead: More apps mean more billing lines, more dashboards to monitor, and more vendors to coordinate for support.
• Higher lifetime costs: Several inexpensive apps can cost more than a single integrated solution that optimizes retention across multiple levers.

The case for consolidation

Consolidating retention features into a single platform reduces complexity and often increases ROI through coherent cross-feature interactions. For example, wishlist data informs loyalty segmentation; review prompts tie into referral flows; VIP tiers can be fueled by referral and purchase behavior. When these systems are natively connected, merchants get clean data, fewer integration points, and a more consistent customer experience.

Growave: More Growth, Less Stack

Growave positions itself as an integrated retention platform that consolidates loyalty, wishlist, referrals, reviews, and VIP programs into one suite. The platform’s philosophy—"More Growth, Less Stack"—is built around reducing tool sprawl while delivering enterprise-level retention features.

Key outcomes Growave targets:

• Increase repeat purchases and customer lifetime value through combined loyalty and referral programs.
• Capture intent with wishlists that feed into reward triggers.
• Automate review collection to improve trust and conversions.

Growave links and where to explore:

• To evaluate pricing tiers and how consolidation affects monthly costs, merchants can compare plans by visiting consolidate retention features.
• For stores that prefer installing via the Shopify ecosystem, Growave is available to install from the Shopify App Store.
• Merchants who want to design loyalty programs that drive repeat purchases can explore how to build loyalty and rewards that drive repeat purchases.
• To see how authentic customer feedback can be centralized and shown on-site, merchants can learn to collect and showcase authentic reviews.

How Growave addresses the limitations of single-purpose apps

• Unified data model: Wishlist saves, referral conversions, and loyalty redemptions all feed a single customer profile. This makes segmentation and triggered campaigns more precise.
• Fewer scripts, fewer conflicts: One vendor manages cross-feature interactions, reducing the chance of front-end slowdowns that occur when multiple apps inject competing UI elements.
• Cross-feature automation: Example use cases made simpler within a single platform:
  • Reward customers who add items to wishlists with a targeted discount if the item remains in their wishlist for a set period.
  • Trigger review requests post-purchase that also invite customers to join a referral program.
• Enterprise support and growth services: Plans and onboarding geared toward scaling stores, including Shopify Plus support.

Growave resources and evidence:

• Merchants can also access inspiration and customer stories to see real-world outcomes at customer stories from brands scaling retention.

Specific feature overlaps and advantages over the two standalone apps

• Wishlist parity plus more: Growave’s wishlist covers basics like multiple wishlists and guest saves, and then layers reward triggers and loyalty points on top — a feature set that turns wishlist intent into repeat behavior. See the wishlist strategy within a larger program by exploring loyalty and rewards that drive repeat purchases.
• Reviews and UGC integrated: Collecting reviews that feed into product pages and email flows happens in the same system, eliminating manual exports and sync errors. Learn how to collect and showcase authentic reviews.
• Consolidated analytics: Instead of piecing together conversion and re-engagement metrics from separate dashboards, Growave provides combined insights that reveal which retention actions increase repeat purchase rate.

Integrations and enterprise readiness

• Growave publishes integrations with popular marketing and customer support platforms. For merchants using Klaviyo, Omnisend, or Recharge, the combined setup reduces the need for custom middleware.
• For Shopify Plus merchants, dedicated flows and higher-tier plans are available; stores can review options designed for scale with the page about solutions for high-growth Plus brands.
• For merchants who want a walkthrough, the team offers discovery sessions that can be scheduled through book a personalized demo.

Implementation considerations and migration path

• Audit current apps: Identify overlapping features (wishlists, loyalty, referrals) that can be retired once Growave is active.
• Phased rollout: Start with wishlist or loyalty to validate data flows and customer response, then enable other modules.
• Data migration: Export wishlist data, referral records, and review history; Growave’s onboarding resources guide the import process.
• A/B test key behaviors: Test reward structures or notification strategies to validate improvements in repeat purchase rate before switching off legacy apps.

When a single-purpose app makes sense even with consolidation

Consolidation is not always necessary. Single-purpose apps may still be preferable when:

• A specific workflow is mission-critical (e.g., share-to-pay for gift registries) and the merchant lacks bandwidth to reconfigure consolidated platforms quickly.
• A legacy system or unique checkout customization prevents a single app transition without extensive development.
• Short-term experiments are needed to validate a hypothesis before committing to a larger integration.

For those scenarios, the approach is pragmatic: use a single-purpose app temporarily and plan for consolidation once the concept proves value.

Practical migration checklist for merchants

• Map which features an integrated platform must cover (wishlist, loyalty, referrals, reviews).
• Export essential data from existing apps: wishlist lists, customer review history, and referral codes.
• Test integrations (email/SMS, analytics) in a staging environment.
• Set KPIs: repeat purchase rate, AOV, conversion rate of shared carts, reactivation rate via wishlist alerts.
• Phase retirements of old apps after validating KPIs post-launch.

Frequently Asked Questions

What types of merchants should pick Ask to Buy instead of Mst?

• Ask to Buy suits merchants who need immediate checkout friction reduction in share-driven purchases: gift registries, parent-pay flows, and enterprise sales rep workflows. If the merchant’s priority is immediate payment completion from a designated payer, Ask to Buy’s pre-filled checkout and share mechanics are purpose-built for that use.

What types of merchants should pick Mst: Wishlist + Marketing flow instead of Ask to Buy?

• Mst is ideal for merchants who want to capture long-term intent via wishlists, send price-drop and back-in-stock alerts, and have a low-cost entry point. Stores that rely on wishlist-driven marketing and already use Klaviyo or push providers will find Mst’s integrations helpful.

How does an all-in-one platform compare to specialized apps?

• An all-in-one platform consolidates data and features, reducing integration overhead and script conflicts while enabling cross-feature automation (for example, awarding loyalty points to wishlist savers or prompting referrals after a review). Specialized apps can be lighter and faster to deploy for a single need but often create more work and higher total monthly costs as features multiply.

If a store uses Mst or Ask to Buy now, what’s the recommended next step?

• Measure short-term outcomes for the existing app (conversion uplift for Ask to Buy; reactivation and purchase rates for Mst). If these tools are delivering clear ROI, keep them while planning for consolidation. If multiple single-purpose apps are in place and the total cost or operational overhead is growing, evaluate integrated platforms and compare feature parity and support. Merchants interested in consolidation can review options and pricing at consolidate retention features or install from the Shopify App Store to test an integrated approach.
