Crossroads Trading Co.

Opened in 1991, the very first Crossroads store is packed with a seasonal inventory of contemporary clothing and accessories for men and women. Located on Fillmore Street (Pacific Heights' main retail drag), it should be no surprise that there's lots of fashionable secondhand treasure to be hunted here. Keep your eye out for incredible deals on designer handbags and shoes, leather jackets and one of the best selections of denim in town. Should the mood strike, you can literally sell the shirt off your back, on the spot—for 33% of the sell price, or 50% in trade. The now-national chain has three other stores in the city.
