All stores price what they sell at differently. You can save some decent money if you were to buy certain items from one store and the others which are cheaper in another store. But hopping from store to store can be a hassle. The better way to go about it and still not miss out on great deals is by planning your spending so you can buy items which are cheaper in one store one week and the next week you'll go to the other store that sells the items you didn't buy, at lower prices. It's better than burning more gas driving to another store . . .
