Repeat fake orders lead to failed deliveries and returns for Cash on Delivery stores. This app hides the Cash on Delivery option at checkout when the customer's phone number or email is on the store's blacklist of customers who repeatedly refused or returned COD orders. Blacklisted customers can still check out with an online payment method, so genuine buyers are never blocked. The check runs inside Shopify checkout with no delay.

• Hides Cash on Delivery for blacklisted phone numbers and emails
• Checks the contact phone, shipping-address phone and email
• One-click on/off and a customer lookup in the app page

Run your checkout rules from one app. Set a minimum or maximum order value, total item count or quantity per product, with "multiple of" rules for packs. Rename, hide or move payment methods, for example to put Cash on Delivery first. Turn on the cart embed so customers see why an item couldn't be added. You can edit every message, and a live preview shows what customers will see. Settings live on your store, so checks run inside Shopify checkout with no outside server calls.

• Minimum and maximum order value, total items and quantity per product
• Rename, hide or reorder payment methods at checkout
• Pop-up cart messages when an item can't be added, in your own words
• "Multiple of" rules for packs, cases and bundles of the same product
• Live preview of the checkout and messages before you save
