Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCartLock protects merchant profit margins by preventing customers from checking out below a set order value. Built natively with Shopify Functions, it executes server-side at checkout without modifying theme files. Unlike older apps relying on cart scripts, CartLock cannot be bypassed by express checkouts like ShopPay, ApplePay, or GooglePay.
LimitLock sets minimum and maximum purchase limits and enforces them inside checkout itself, server-side. Because enforcement happens in checkout rather than in cart scripts, rules apply on every purchase path, including accelerated checkouts. Set min and max quantities per product, variant, or collection, plus order-wide item and subtotal limits. Shoppers see which limit they hit and how to fix it.
