Mars Mercantile is located a couple of blocks away from the UC Berkeley campus, on Telegraph Avenue. Most of their clothes are purchased from people, and then resold. They are very picky about their selection, and only purchase items that are in good condition, are cool and fashionable, and that their customer base will probably like. Rummaging through that store is a total adventure. You can find used designer duds, funky retro pieces, gently worn classics, and more. Many thrift stores carry clothes you'd be embarrassed to walk around in. Mars offers a selection of merchandise you'd be proud to strut around town wearing. If you are into vintage, unique pieces, and paying less for cool clothes, you should check out Mars. Their prices are reasonable, too. Though, they usually cost a little more than most normal thrift stores.
