A method of purchasing goods and services in combination with a gaming feature is described. Consumers are provided with a bank card which acts as a means of identifying consumers, extending credit to them and communicating purchasing data to a centralized location. A pool of funds is established in relationship to the use of the bank card by consumers. Periodically, a lottery is conducted for distributing prizes to consumers by distributing proceeds from the pool of funds.
