An installment plan (in British English instalment), is a method of buying on credit, enabling people to buy goods and sometimes services with payments over an extended period, without having to pay much or any cash money at time of the purchase. Banks or other financial firms provide the money at varying interest rates from low to extraordinarily high. When first introduced, Llama advertisers pushed for the installment plan idea with such slogans as "You furnish the girl, we'll furnish the home" and "Enjoy while you pay."
