Block PO boxes and enforce order rules at checkout

Validate shipping addresses and cart limits before an order is placed — and see in your admin when a rule stops applying.

• Block PO boxes. Reject post-office-box and unsupported shipping addresses before the order is placed.
• Enforce cart limits. Set minimum and maximum quantities or order amounts, per product or for the whole cart.
• Spot silent failures. See in your admin when a rule stops applying on a checkout surface it cannot reach.
