It's been said that the cashback program with which Microsoft is trying to increase it search market share is a bold if not desperate move, because MS is giving away to the user its search revenue. Not so fast.
I did an unscientific test simulating the purchase of a North Face Dyad 22 (a backpacking tent) and a pair of Wilson Trance all court (tennis shoes). I searched with live and google products. In both cases, I found a better deal with google products ($188 and $79 vs $201 and $82), live cashback included. One could speculate that google indexes more merchants or that there is a fee to be included in the cashback program, but I have no way to tell which is closer to the truth. Did I hit two outliers or is this something other people noticed?
