BlockCart: Checkout Validator

Prevent unwanted orders with cart rules and multi-condition checkout validation.

Stop bad-fit orders before they become fulfillment headaches. Create checkout validation rules that block unwanted purchases by ZIP or postal code, shipping address, products, collections, product tags, SKU, quantities, cart total, customer tags, login status, country, company, discounts, and cart attributes. Combine multiple conditions for local delivery, product restrictions, order limits, B2B rules, and customer eligibility. Show a custom checkout error message when blocked.

• Block or validate orders with multiple checkout rules.
• Display warnings and messages on product pages, cart pages, and during checkout.
• Import & Export to move rules between stores.
