I'm not sure if quantity purchases are or will be handled, but in case not. If there is a placed order for an item it would be good to display it whenever the user attempts a second purchase. Maybe there are better ways for handling this, but I want to be sure multiple purchases are allowed, and a minimal protection for involuntary multiple purchases is taken.
Hello, Quantity purchases at enabled through the "Add to Cart" functionality. Customers can purchase multiple quantity of the products by specifying the quantity in the cart. The "Add to Cart" feature is available in the Amazon provided product detail page. Thanks you Mudeem
