Charity shops sell second-hand (used) items at very cheap prices: clothes, shoes, bed sheets, etc. They are called this way because the money they get goes to charity organisations, like The Red Cross, Oxfam, Save the Children…

They are usually open from Monday to Friday, and Saturday only in the morning.
