I always leave Costco a bit traumatized by my receipts. When you're spending $24 on paper towels alone, the bill adds up fast. But even though buying in bulk costs more upfront, it's usually cheaper in the long run (that's actually the whole point, of course).
The question is: how much cheaper is it? Is it really worth it to have to stash all those big bottles and tubs just to save a few cents (not to mention the cost of membership)? Could Target, which is known for rock-bottom bargains on household goods, beat Costco's bulk prices?
