He's mad as hell about grocery discount tactics
The solution can be as simple as using a bit of basic math to verify that you truly are getting the discount that you think you are. When the store offers you a two for one deal, don't assume that buying two of the item will save you money. Take your total cost for the items and divide it by two, then compare that price per item to the regular price for buying just one of them. Often times you'll find that the only advantage to be had is that the store has sold you a second item.
