Don't blame Bing. It is the store that is deciding to charge you a higher price.

I have seen this several times, on both newegg and Buy.com. Normally the "add to cart to see price" type items are cheaper if you don't do the bing cash back

Yeah, I also think this is the merchant's fault. (full disclosure, my wife works for a competitor of Bing Cashback)

My wife's company runs into this issue, and they try to stop the merchants from raising prices, but sometimes a few companies slip through the cracks.

However, maybe Bing doesn't make this against their ToS. In which case, that's bad.
