"A
Trade Exchange or Barter is a type of trade in which goods or
services are directly exchanged for other goods and/or services,
without the use of money. It can be bilateral or multilateral, and
usually exists parallel to monetary systems in most developed
countries, though to a very limited extent. Barter usually replaces
money as the method of exchange in times of monetary crisis, when
the currency is unstable and devalued by hyperinflation." –
