Looks like a load of BS to me, why pay money to join this. You can join ebates.com for free and it is more well known than this. And it works like a charm. Plus we can find better deals here on this website than any affiliate marketplace will ever have.
It is the club member’s responsibility to keep up with the accuracy of their own account and to request rebate money when their accounts exceed $5. Any qualified cash rebates not requested for, and redeemed, by a member from his or her account within 6 (six) months become the property of SuperRebateClub if you have not logged into the “CLUB” website during this period of time. The “CLUB” is not responsible for any changes in the rebate program, and reserves the right to terminate memberships if we think it is in the best interest of the “CLUB” to do so. Assigning, exchanging, selling, or transferring cash rebates by members is strictly prohibited by the “CLUB”.
It is the same thing as what you posted, only it is free to join. You get 2 - 10% cash back when you purchase items from the merchants they have listed.
