While many thrift stores (also known as second-hand stores or consignment stores) are owned and operated by major charities like Goodwill, the Salvation Army, or local charity groups, others are privately run. The shops run by charities mostly offer items for sale that were donated, while private thrift shops buy cheaply and sell at a markup. Consignment stores allow individuals to sell items through the store, taking a commission on the sale. You can find great bargains at thrift stores as some of the items are almost brand new (some have never been used at all) for much cheaper than a brand new item would cost.
