Buffalo Exchange is a national thrift chain that mainly sells modern, designer-brand and trendy clothes for about half the original price. Shoppers can also try selling their old clothes back, garnering better sales if the clothes are in-season and in good condition. The stores vary widely from each other, with some offering better deals than others, but the Dallas spot is a winner. It's easy to get lost for hours shopping in the Greenville location. High-end designer brands are available, not exactly for cheap, but much cheaper than they were new, and the store carries plenty of trendy clothes that are actually dirt cheap — think Forever 21, but on sale. All of these clothes are geared for younger people on various budgets, and that's what makes the store such a fun, friendly place to shop. On Saturdays and Sundays, the friendly hang-out is crowded with shoppers in their 20s and 30s and salespeople who aren't shy about making conversation on topics that have nothing to do with retail.
