BeFrugal has only worked on 1/10 of my eBay purchases. Each time, I made purchases of around $1,000-5,000. I made sure that all my purchases were within their valid categories and was careful not use any other coupon codes. When I contacted customer service, they gave the generic response that they cannot look into cash back inquiries for that site. I am thinking they did not want to pay out... I lost a over $400 cash back by choosing BeFrugal over Ebates and not using any of my eBay coupons in the process. I wish they would at least give a clear explanation what went wrong.
