Online retail giant Amazon has launched a new service to lure in even more customers. Their TextBuyIt service enables people who are on the go to buy stuff from the website with only a text message. Well, actually with two text messages and a phone call (by Amazon to the customer).

"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. It's incredibly simple and convenient," said Howard Gefen, Director of Amazon Mobile Payments, in a statement released by the company.

How the new system works is quite simple. First of all, you need to send in a text message to Amazon with the name of the product, search term or a UPC or ISBN code, depending on what you want to buy and how much do you know about it. The company claims that in only a matter of seconds, it can reply with a list of precise choices including their prices. A second text message by the user confirms a certain item from Amazon's text message and the order is thus placed.

However, final order confirmation will have to be done by phone. Amazon will call the customer on their cell phone to confirm or cancel the new order, which finalizes the process. Of course, for you to be able to order in the first place, you need to already have an Amazon account, and have it set up to be used with Amazon Payments, more precisely mobile payments.

You can use the following carriers with Amazon TextBuyIt: AT&T, Alltel, Boost, Midwest Wireless, Nextel Communications, Sprint PCS, T-Mobile, Verizon Wireless and Virgin Mobile.
