Offers a $15 rebate on any recent purchase through a given vendor after that transaction is made. You are told you are charged $3 to trial their service. When you go to get your rebate, there is no way to get it for your purchase because there is no mention that they will only rebate purchases from PayPal transactions despite advertising you will get a rebate on your last transaction. If you do attempt the PayPal option, your rebate options are a gift card or a check in the mail. Scam.
