Prevent grouping of items in cart

[pljspahn]

I've been using django-cart for a basic app to sell physical products. It's simple and has worked okay for me so far.

I'm now working on adding Gift Card products where the price is chosen by the customer. The model this is based off is just a one-off model to change the name/description/etc. Price is chosen on the detail page.

This presents a problem as when I add a gift card to the cart for $50, and subsequently add another to the cart for $100, the cart sees both items as $100 instead of creating a separate line item for each.

Is there a way for me to prevent this item from grouping together without having to create model entries for all available prices?
