Weasleys' Wares was a small business created by the Weasley twins in the early 1990s, when they were at Hogwarts. They exchanged Bertie Bott's Every Flavour Beans, Cauldron Cakes and Pumpkin Pasties for Famous Witch and Wizard Cards, Chocolate Frogs, pages from the Folio Bruti and passwords to enter Secret passages at Hogwarts. They also had bets during the Triwizard Tournament.
