It seems that all those lovely discount cards feed the computers who can tell how much you are willing to pay for an item then offer coupons for that price.
Seems that people will need to be very careful chopping online where prices are not physically posted on the shelves- they price you pay may not be the price someone else pays.

The article glowingly mentions the "discounts offered" but what if the goal is to figure out the exact minimum they need to discount to get you to buy? You could end up paying more than another, more stingy shopper.
