Buffalo Exchange is a family-owned resale fashion chain founded in Tucson, Arizona in 1974 that pioneered the buy-sell-trade model for secondhand clothing. Customers bring in gently used, on-trend clothing and accessories and receive cash or store trade on the spot, while shoppers browse a hand-picked mix of current styles, vintage finds and designer pieces at a fraction of retail. With roughly 40 stores across the United States and about 590 employees, Buffalo Exchange has built a business around affordable, sustainable style, keeping millions of garments in circulation each year and channeling small change into local charities through programs like Tokens for Bags.
