  • a database including information about at least one commodity including quantity units and a current time unit purchase price; and

    a web server computer for interacting with the database and also for interacting with at least one client computer configured to be used by a purchaser, the web server computer designed to allow the purchaser to;

    establish a bulk refillable account capable of having a balance in quantity units for the commodity;
