BlockCart: Checkout Validator

BlockCart: Checkout Validator helps you prevent unwanted orders by setting up checkout validation rules that block purchases before they create fulfillment problems. Control orders using ZIP codes, postal codes, shipping addresses, products, collections, product tags, SKU, quantities, cart totals, customer tags, login status, countries, companies, discounts, and cart attributes. Create multiple checkout rules with combined conditions to manage local delivery restrictions, product limits, order minimums, B2B requirements, and customer eligibility. When an order gets blocked, customers see a custom error message explaining why they can't complete their purchase. Display warnings on product pages, cart pages, and during checkout. Import and export rules to easily move your validation settings between stores.
