Frequently asked questions

Yes. The app is free on live stores. There is no subscription, no trial that converts, and no rule count cap imposed by the app. Shopify's own limits still apply: 25 active discounts and 25 active customizations per API, and a 10 KB configuration per rule.

No. Discount, payment customization, delivery customization, cart and checkout validation, and cart transform Functions work on Basic, Grow, and Advanced through this app. Shopify keeps a few operations for Plus: cart transform line updates, payment terms and B2B order review, and hiding or renaming the main credit card option on US and Canadian stores.

Uninstall it from Shopify admin under Settings, Apps and sales channels. Your Functions stop running when the app is removed.

No. Shopify Scripts stopped executing on 2026-06-30. Line item scripts map to discount Functions, shipping scripts to delivery customizations and shipping discounts, payment scripts to payment customizations.

Not automatically. You recreate the rule in the builder, usually in a few minutes, and support helps when the mapping is not obvious. Shopify does not allow public apps to run merchant-written code.

Two reasons cover almost every case: combinations are not enabled on both discounts for each other's class, or both are product discounts targeting the same product. Shopify applies one product discount per cart line.

No. Shopify accepts a valid code before the Function runs. The Function can withhold the amount when conditions are not met, but it cannot remove the code or show a custom message.

No. A Function can discount an eligible gift to free but cannot add it. The customer or a storefront feature has to add the gift product first.

To all qualifying units in the group, using the single highest tier reached. Tiers do not stack and do not apply only to complete multiples.

The cart page is rendered by your theme; the Function calculates at checkout. If the checkout total is right, the discount works. Storefront display is a theme setting.

Rules match Shopify's internal method name. The card option is usually Shopify Payments or the provider name (Stripe, Adyen, Braintree), not Credit card. Use a contains match on one distinctive word.

Only on Shopify Plus. For stores in the United States and Canada that are not on Plus, Shopify ignores hide, rename, and move operations on the main credit card option. Every other method can be customized.

Yes. A delivery customization can hide a named rate when the cart contains matching products. To change the price instead, use a shipping discount.

No. When a validation matches, Shopify blocks the whole checkout with your message until the cart changes. It cannot remove items, reject a discount, or stop quantity changes in a cart drawer.

Set it live, then check out with a real cart on your store. Inactive rules do not run, even in tests. Check the checkout rather than the cart page.

Shopify's 10 KB configuration limit per Function. The meter shows how much of it your rule uses. Long product lists are the usual cause; use collections or tags, or split the rule.

Yes. Fast support in the app chat helps build and check rules. The app holds 5.0 stars across 110+ Shopify App Store reviews.
