Bing sent notice to at least some merchants (probably all) today indicating that they will be matching all cashback discounts starting August 10. It doesn’t specifically say that it ends Aug 31, but it says “during August” so I assume that means it ends on or before the 31st. They will also begin a broad marketing campaign designed to
increase traffic to and awareness of Bing Shopping and the cashback program.
If you aren’t live on Bing yet, now is a good time to get started.
