UR: Limit 1 Item Per Customer

The UR: Limit 1 Item Per Customer app helps ecommerce merchants limit purchases to one item per customer automatically, preventing overselling and ensuring fair access. It is ideal for limited stock items, exclusive products, or campaigns where fairness matters. The app displays clear error messages to customers, reducing confusion and support inquiries. Integration with the Cart and Checkout Validation API ensures reliable enforcement without disrupting the shopping experience.
