How it sells itself

Cart Lock offers customizable conditions to block unwanted purchases based on specific rules such as country, product quantity, customer profiles, discounts, markets, and more—making it ideal for stopping bots. With real-time validation powered by Shopify Functions, it ensures only valid orders are placed. Transparency is maintained through clear warnings, keeping customers informed.

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.

Key points
  • Block customers by country blocker, amount, minimum order quantity limits.
  • Block fraud orders, block shipping, zip codes, states and block 0 orders.
  • Validate orders, block cart currency, discount amounts, customer tags, company.
  • Block country. Show warnings on cart, product pages and during checkout.
  • Edge checkout validation powered natively by Shopify Functions.
  • Blocks 1-click & express checkouts including ShopPay, ApplePay & GooglePay.
  • Custom error messages with dynamic {minSpend} and {subtotal} variables.
