I have been a member of Upromise since August 2006. My credit cards are registered with them, as well as my grocery cards. The majority of my shopping for non-food items is online. I always check Upromise before making a purchase. I have only earned a little more than $200 in the past eight years. I would say that at least 50 percent of the time I do not receive credit for my purchases. Somehow there is no record of me accessing partner sites through Upromise.
