@dprophitjr As a side note: Milk from non-antibiotic cows would be a feature! =) Unless, it had a specific EAN-13/UPC code. Then, it's an attribute in this shopping cart so that you can use the multi-product combo wizard to state specific EAN-13/UPC types. EAN-13/UPC is linked data in semantic web. The manufacturer often includes nutritional information, liquid volume and weight and the like.
