Seattle - Online retail giant Amazon.com (NASD: AMZN) on Wednesday announced the launch of a new feature that lets consumers use text messages to find and buy products. "With TextBuyIt, if you're walking out of a concert and want to buy a CD from the artist you just saw, or if you're at dinner and a friend tells you about a great book you should read, all you have to do is get out your mobile device, send a text message to Amazon, reply to the response, confirm your order, and your item will be on its way," said Howard Gefen, director of Amazon Mobile Payments.
