ISnipcartItem..::..Stackable Property

When you set this attribute to false, adding the same product to the cart will result in two distinct items in the cart, instead of simply increasing the quantity. For instance, when your customers click twice on the same Buy button, they will have two entries of the product in their cart, instead of having a quantity of 2 for the same product. This is useful when you have a product with specific custom fields requiring different information for each occurrence. For instance, if you’re allowing your customer to engrave a message on your product, this will allow them to specify a different message for every item. When not defined, this property is considered to be true by default.
