Kerstin and Spencer Block founded Buffalo Exchange in 1974 in Tucson, Arizona, and the Pacific Beach outpost at 1079 Garnet Ave in 92109 brings that same buy-sell-trade model to San Diego's busiest beach corridor. Kerstin and her daughter Rebecca still run the company, which has grown to roughly 47 locations nationwide while remaining a privately held family business. The PB store sits on lower Garnet near Tavern at the Beach, drawing a mix of college students, tourists, and thrift-savvy locals looking for vintage denim, designer labels, and seasonal finds at resale prices. Buffalo Exchange's Tokens for Bags program, launched in 1994, replaces single-use plastic bags with charitable donation tokens and has generated over $893,000 for local nonprofits across all locations. The Pacific Beach store manager listed on business filings is Julie Barnell, and the staff buys and prices inventory on the spot, so the selection rotates daily. Shoppers who work up an appetite sorting through the racks can head a block east to PB Sushi on Garnet for a quick lunch. Men's and women's clothing, shoes, and accessories fill the racks, with a strong emphasis on current trends and recognizable brands at resale value. The store is open daily, with weekday hours running until 8 p.m.
