I'm selling digital content. Is there an ability to forbid the buying of the same product twice on an order. I understand that the store seems to be geared to physical products where someone might be wanting multiple products.
But with digital, they don't want to buy the same thing twice....
Is there a switch where I could force the buying of only one product during the order?
Ahhh right... So you can do that with no code, or write some code to handle it. You can use javascript in the cart.php page to check quantities and throw a message and disable the checkout button if any product has a quantity of more than 1.
