No more than one piece per hand OpenCart

Do you want to implement the sale of digital products on OpenCart? Then you definitely need a modifier that prohibits adding the same product to the cart in an amount of more than one piece. After installation, the buyer will be able to add products to the basket only in the amount of 1. Even adding the product again, the buyer will still see the product in the basket in the amount of one piece 1. Also, the buyer will not be able to change the quantity of the product on the basket page, placing an order - it will always be equal to one.

Selling products in one copy is suitable for information products, since it makes no sense to sell one file to the client in the amount of 2 or more. Selling products in only one piece can be useful in other cases - for example, if you sell unique products, such as antiques, coins. Or you want to sell one copy of the product in one hand.

When changing the quantity of products in the cart or on the checkout page, the module will not allow to increase it by more than 1.
