Have you ever wondered what kind of difference your browsing history can make when you shop? We were surprised to see this before/after photo that reader David sent. He tells us that he was shopping Hotwire for car rentals and took screen shots before and after he cleared out the cookies in his browser. It’s striking how different prices are when Hotwire thinks that he’s a new visitor who has never been to the site before. Source... Wonder how many other sites engage in this kind or activity? What ever happened to the concept of rewarding repeat customers instead of shafting them?
