Microsoft has announced on the Bing Community blog that they will be shutting down their Bing Cashback service. Bing Cashback was a feature on Microsoft's search engine, Bing, that allowed you to save up to 10% from certain vendors on certain products using Bing Shopping. Microsoft lists poor adoption as the main reason for this shut down. It will shut down on July 31st at 12am ET or July 30th at 9pm PT, so until then save some money. After that you will have a year to redeem any earned Cashback in your account. They do state this, which may hint at some more possible shopper features in the future:

Shopping remains one of the most important tasks people engage in while using search, and we remain committed to delivering great shopping experiences for you that help you make better shopping decisions, get great deals, and save time and money along the way. For merchants and advertisers, we have some ideas for making it easy to get a broader array of products and offers into Bing, and we’ll share some details on this later this summer.
