Does Bing offer negative cashback?

Would you believe that a cookie, a single cookie, could make your Christmas shopping cost more?

That's right, and this cookie, well it doesn't win an award for taste, it isn't ginormous and it doesn't even have gold speckles in it. It's just a small file on your computer that tracks where you have been. At least one retailer is making use of a cookie from the Bing cashback program to charge you more!

John Puskarich, co-founder of deal comparison site Bountii, shared the new negative cashback feature on the company blog highlighting one example of how using Bing's cashback service could cost you more.
