おひとり様一点一回限りの購入制限アプリ

This app allows for setting a purchase limit of one item per customer with just one click. It automatically checks the purchase history of logged-in customers to prevent repeat purchases and displays messages accordingly. The app also blocks actions like adding to cart for customers who have already made a purchase or are not logged in. It is recommended for sellers of limited edition or trial products who want to manage the one item per customer rule automatically.
