Cartridge World, tucked in the corner next door to Volleys Tennis Shop on G Street, is a tiny shop that provides recycled ink cartridges for printers. In addition, it sells refurbished printers and will take your used ink cartridges in exchange for a small discount off the items sold at the store. The store itself is almost a closet, with one small counter and a few shelves carrying the surprisingly large selection of recycled ink cartridges. Cartridge World claims to carry all ink cartridges for HP, Lexmark and Brother.
