Limit purchases to one item per customer to prevent overselling and ensure fair access.

This app prevents duplicate purchases by enforcing a one item per customer rule at both cart and checkout. It is ideal for limited stock items, exclusive products, or campaigns where fairness matters. By displaying clear error messages on product and cart pages, customers immediately understand purchase restrictions, reducing confusion and support inquiries. Integration with the Cart and Checkout Validation API ensures reliable enforcement without disrupting the shopping experience.
