Credit cards know how much you spend at Whole Foods with a certain transaction amount. This I always assumed was tracked and could be used/sold by the credit card companies. This article tends to imply that MasterCard is getting the actual list of things that you buy at a store. I would hope that for this to happen the store must also be involved in selling the individual item list to the credit card company. I was hoping that stores were not doing this or I would have heard something about it, but maybe it would not really be news at this point in the data selling game.
