Lockdown: Cart/Checkout Rules

Lockdown: Cart/Checkout Rules is a Shopify App that allows ecommerce merchants to create custom validation conditions to block risky orders and enforce checkout rules without the need for coding. Merchants can set rules based on cart value, quantity, products, collections, customer type, shipping destination, or delivery method, and use AND/OR logic for precise control. The app is perfect for preventing fraud, enforcing minimum orders, restricting B2B products, blocking high-risk regions, and meeting compliance requirements. Rules run at checkout and display custom error messages to customers.
