This shopping experience is unlike most. It buys, sells or trades used and new clothes. You can come in and sell clothes, walking out with money, or maybe you'd just like to trade what you have for some different clothes with no money exchanged. The Buffalo Exchange also only sell jeans for guys. It's a small store, and it doesn't take long to look everything over. For women, there are a lot of tops, bottoms, accessories and even Halloween costumes.
