Rummage sale

A jumble sale, bring and buy sale (U.K, Australia, occasionally Canada) or rummage sale (U.S and Canada) is an event at which second hand goods are sold, usually by an institution such as a local Boys' Brigade Company, Scout group, or church, as a fundraising or charitable effort. A rummage sale by a church is called a church sale or white elephant sale, frequently as part of a church bazaar.

Organisers will usually ask local people to donate goods, which are set out on tables in the same manner as at car boot sales, and sold to members of the general public, who have paid a fee to enter the sale. Typically in the UK the entry fee is somewhere between 20p and £1.

Jumble sales may be becoming less popular in the UK, as car boot sales and the World Wide Web enable people to sell their unwanted goods rather than donate them to charity.

Rummage sales in the United States as a rule do not charge any entrance fee, but sometimes charge a fee, or reserve for paid members or donors access to "preview sales" before the general public is admitted. Sometimes the sponsoring organization excludes donations of certain items, such as furniture or exercise equipment, or have a sale restricted to a single type of goods, such as book sales or sports-equipment sales.

Some larger churches or charities have permanent "thrift stores" where donated goods are offered either daily, weekly, or monthly, etc. The Salvation Army and Goodwill Industries are known for their daily-operated thrift stores, frequently located in donated space in major retail locations. Other "thrift stores" are either for-profit, or operated by corporations which are a charity in name only, as only a small fraction of profits are used charitably.
