I seem to remember an article about a guy who would go into used book stores, and using his Iphone or whatever, would scan the barcode. If he could sell the book on amazon for more than what the bookstore was selling it for, he would buy it.
For the life of me, I can't remember where I read this. Does this sound familiar to anyone else?
