Davis Square’s bargain retail profile recently kicked it up a notch with the addition of Buffalo Exchange (on the same block as Poor Little Rich Girl and Good Will). Giving national chain a good name, Buffalo Exchange allows for direct sale or trade of used clothing and accessories, and carries both classic pieces (such as the J. Crew print dress I scored for $23.50...sweet!) and quirkier ones. The two-level store currently offers more goods for women (including rows upon rows of shoes downstairs), though there are some racks for men. Laurel loves treasure hunting with me in Davis; she only requests that this and other stores start carrying used kid’s clothing.

Buffalo Exchange, 238 Elm Street, Somerville; 617-629-5383
