BlockCart: Checkout Validation

BlockCart: Checkout Validator is a Shopify App that helps ecommerce merchants prevent unwanted orders through cart rules and multi-condition checkout validation. It allows merchants to create rules based on various parameters such as ZIP or postal code, shipping address, products, collections, and more to block purchases that do not meet specified criteria. The app offers flexibility in setting up rules for local delivery, product restrictions, order limits, B2B rules, and customer eligibility, and provides custom error messages when a purchase is blocked.
