It's easy to be ripped off the net if you don't look around at similar web-sites before deciding to buy a product. When a publisher releases a book, then quite naturally, they slap a price on the book. A price which all book sellers should sell the book at. But looking around the net you'll find price differences of up to $5 [same book!] Why do some book sellers hike up prices? Do they get lower bulk discounts so they just have to make some extra money from an unsuspecting buyer?
