From the Associated Press: "First, Papa John's customers register online to create accounts. They can save up to four favorite orders, along with a delivery address and payment preference. Customers can punch in 'FAV1,' 'FAV2,' 'FAV3,' or 'FAV4,' to text message orders. Papa John's sends a reply with the order, and the customer can confirm or change it." [via "Girl Slice"]
