Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureSome orders should never happen: an accessory checking out without its base device, two products that can't ship together, or a bundle item bought again on its own. CartGate blocks these carts before checkout. Set rules by product, variant, tag, or collection, and choose to block the cart or warn the customer on the product page.
CartLock 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.
