Since 1997, this upscale secondhand store has been a socially-minded bargain hunter’s haven: Proceeds from the gently used designer samples and vintage treasures benefit the Lower East Side Service Center, a non-profit that assists individuals suffering from chemical dependencies, HIV/AIDS and mental illness. Angel Street receives new merchandise several times a day through donations from individuals and corporations, meaning you’ll stumble upon one-offs like a pair of never-before-worn J. Crew gingham capri pants ($15) as well as an entire rack of Anna Sui logo tees ($6 each) direct from the supplier. If you’re redecorating your apartment, make this your first stop: The furniture selection is especially strong, and can turn up a full-size foosball table ($300), ergonomic office chairs ($40), a sturdy wood table ($80) or a Rosenthal crystal centerpiece bowl ($100). Unless you’re a masochist, don’t bother peeking in the windows before entering: Prime finds like Knoll chairs and Lambertson Truex handbags are displayed behind glass for up to two weeks before going on sale, at which point shoppers queue in the early morning to snatch them up quicker than you spotted them.
