The OpenCart extension "Purchase Once" allows you to limit repeat purchases of the product by the customer. It is also possible to limit the quantity of each product in the cart to one copy (works when using a default shopping cart system).
The extension can be useful when selling digital products, when only one copy of the product is provided to one customer. Or in other cases when you need to make a one-time purchase of a product in the OpenCart system.
If the customer tries to buy again, the product will not be added to the cart and an error message will be displayed: "You have already purchased this product! Your order #1". Button "Add to cart" will be hidden on the pages of products that have already been purchased.
Module installation instructions:
Upload the module in the admin panel in the "Extensions" : "Install".
Go to the "Modifications" section and update the cache.
Go to the "Dashboard" section and update the template cache.
