Great service. Very responsive when you need them. The app does exactly what you need and gives you control over so many options from shipping customizations to discounts, and combos. I've been using shopify for nearly 20 years and this is probably the most responsive team behind a product I've ever encountered.

Excellent app and outstanding customer support!We needed a specific checkout validation for products that are only available as part of Shopify Bundles. Mira was incredibly helpful, took the time to understand our requirements and carefully checked the possible limitations.After testing, everything works exactly as intended: individual purchases are blocked, while the complete bundle can proceed through checkout.A great solution, especially for a free app. Highly recommended!

About ShopDigest

The Shopify ecosystem, shown through the work

ShopDigest is an independent directory of Shopify work. Developers, agencies and experts publish the projects they’ve actually shipped — migrations, rebuilds, custom apps, headless storefronts — with the results attached.

For merchants, that means judging a partner on evidence instead of a sales page: browse real builds in your category and budget, then reach out directly. For builders, it means one profile that keeps working after the project ships.

No commissions, no pay-to-rank placements. The best work rises because people save and follow it.
