Housing Works has got to be our favorite bookstore/thrift store/AIDS outreach and service center, if we had to choose one. The relentless nonprofit is at it again this weekend, hosting a pretty incredible sample sale, boasting more than one-million bucks' worth of designer duds, all at 50-70% off. Get your shop on for a good cause: the sale benefits HW's Women's Health Center, which opened last year in Brooklyn.
