I don't care that they can profile my purchases - I care about the fact that the whole program adds up to more overhead and poorer service in the long run that costs MORE!!!!
Since the store can't figure out that they need to increase the amount of a brand they carry when it is out of stock 3 days a week - and the compeating brands have layers of dust on them, why pay for card readers and computerized profiling. they won't use it for the customers benefit.
