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 nonprofit that assists individuals suffering from chemical dependencies, HIV/AIDS and mental illness. Angel Street receives new merch 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. (Prices range from $20 to $3,000).
