A pricing scheme where the purchaser pays an amount of their choice rather than a fixed price.
A pay-what-you-want pricing scheme may include a minimum payment. In this case it is usually worded as, for example, "Pay $1 or more". This amount may be as little as $0.01.
The pure form of pay-what-you-want pricing includes the option to pay nothing at all.
Sometimes, pay-what-you-want is used in conjunction with a charity drive, with a website that allows purchasers to divide their payment between the artists and charities involved in the sale.
