An Amazon Service for the College Crowd

Amazon launched a peculiar service where you actually text information to Amazon and get results back as to whether or not Amazon stocks the product and at what price. You then reply with either a 1 or a 2 (if gives you only two options in its response text) at which point it prompts you for an e-mail address and zip code.
After texting that information to them, you receive an automated phone call to complete the ordering process. The interesting thing here is for book buying time for college students because you can type in an ISBN or UPC to do a price check with amazon, and if they have it at a lower price, you can go ahead and buy it right then. Nice to have an alternative to the highway robbery of most campus book stores.
