| A text message showing book prices received via Amazon.com Inc.'s TextBuyIt shop-by-cell phone service is shown in New York, Wednesday, July 23, 2008. If you're in a store and want to compare prices on something that seems appealing, you can text the item's name or bar code number to "262966," which corresponds with "AMAZON" on the phone keypad. Then the service sends back matching items available for sale on Amazon. (AP Photo/Dan Goodman) |
