I just noticed that Microsoft rewards has added Bing Rebates (BETA) on selected account now. It has very limited participating retailers right now, but they should add more retailers soon since it's still in BETA stage. It's good to see MS brings cashback feature and hopefully it will well compete with other cashback sites.
