Lockdown lets you create powerful cart validation rules without code. Block orders based on cart value, quantity, products, collections, customer type, shipping destination, or delivery method. Combine conditions with AND/OR logic and nested groups for precise control. Perfect for preventing fraud, enforcing minimum orders, restricting B2B products, blocking high-risk regions, or meeting compliance requirements. Rules run at checkout and display custom error messages to customers.

• Create unlimited validation rules with custom error messages for checkout
• Block orders by cart total, subtotal, quantity, or specific products
• Restrict by shipping country, province, ZIP code, or delivery method
• Target B2B customers, authenticated users, or specific company names
• Combine conditions using AND/OR logic with unlimited nesting levels
