I used Ebates for many years prior to starting to use Coupon Cabin. I've only made 2 transactions so far through them but I've found it easeful, decent cash back percentages, and their customer service has been very prompt, professional and clear. I just get so nervous about ensuring that I clicked on the button and my cart was empty to start that sometimes I feel like I have to go back a couple times to start + process the transaction, a small price to pay for a rebate, but I still don't always "trust" the technology to capture my purchase.
