You can already order Domino’s Pizza online or from your cell phone, and now TiVo has added the service to its menu. Ask for delivery or pick-up, then track the delivery from your TV. Although there is no charge for the service, you will have to look for the take-out restaurant’s advertising entry points and click on “I Want It.” Set up a user name and password on Domino’s site or enter your address on TiVo, then build your own. You have to pay by cash when it comes, which they say should be within 30 minutes.
