Fortunately Amazon.com launched this service on 4/2, or we might have wondered ...
In less than a minute and using only text messages, Amazon.com customers can find the product they are looking for and complete a purchase using TextBuyIt. Simply send a text message to "AMAZON" (262966) with the name of the product, search term or a UPC or ISBN code, and, within seconds, Amazon replies with the product or products that match the search, along with prices. To buy an item, customers simply reply to the text message by entering the unique single digit number next to the item they want. Customers will then receive a short phone call from Amazon with the final details of their order and asking them to confirm or cancel the purchase.
When customers choose to purchase something for the first time using TextBuyIt, they will be asked for their e-mail address and shipping ZIP code they use for their Amazon.com account. With this information, Amazon uses customers' default settings for payment method, shipping address and shipping speed, including 2-Day shipping for Amazon Prime members.
We tried this, and yes it works, and yes, it's easy. However, the most likely use for this is not shopping, but price comparisons! That's probably what Amazon.com had in mind, to stop the "I wonder what price this is at Amazon.com? Nah, let's just buy it here" scenarios.
