FedEx and UPS often reject P.O. Box and military (APO/FPO) addresses, causing fulfillment delays, returned packages, and extra shipping costs. PO Box Blocker solves this by automatically validating shipping addresses in real-time during checkout. If a customer enters a restricted address, they cannot complete the purchase until they provide a valid physical address. You can also block specific states or zip codes to fully control your shipping zones. Set up in seconds.

• Automatically block P.O. Box, APO, and FPO addresses during checkout.
• Restrict shipping to specific states, provinces, or zip codes easily.
• Seamless Shopify Checkout integration with zero coding or theme changes.

Bundle Stock Sync is the ultimate auto-sync solution for merchants selling bundles, kits, or multipacks. When a customer buys a bundle, component stocks decrease instantly. If a component sells out individually, your bundle stock automatically updates to prevent overselling. Simply map multi-item bundles using custom multipliers (e.g., 1 Bundle = 3 of Item A). Everything runs flawlessly in the background, maintaining 100% accurate inventory.

• Auto-sync inventory between bundles and base products in real-time.
• Set custom quantity multipliers for items inside your multi-product bundles.
• Track all stock adjustments instantly through a detailed synchronization log.
