Imagine if you will a bot that could not only add the item to a wishlist, but could ALSO get your location from your iPhone, read the barcode, and respond with a message that says "Hey, you're standing in FYE and that movie is $25 here, but at the Virgin Records two blocks down it's only $20."
Actually, their was a service that you could use with a cell phone that worked like a moblog, only you send in your image and it responded with like the top five lowest prices for the item. I forget the name of it though, I believe it's defunct.
What you need in there Darren is a little grep and cut ninja action to pull the barcode out. Lemme play with the output here and getcha some commands.
