Apps merchants weigh against BlockCart: Checkout Validation, with their own detected stores and ratings.
Block checkout for PO boxes, ZIP codes, order limits and B2B rules. Test rules before going live.
Block bad-fit orders before they create cancellations and fulfillment work. Build no-code cart and checkout rules with multiple AND/OR conditions. Set minimum order quantity (MOQ), minimum cart value, and maximum quantity or value limits. Restrict products or collections by ZIP code, postal code, country, customer tag, login status, or company. When a rule matches, BlockCart stops checkout and shows a clear custom error so the buyer can fix the cart and continue.
Every number on this page comes from public storefront scans and the public Shopify App Store listing. If Shoplist shows BlockCart: Checkout Validation on a store, it is there.
