I liked it initially where you wait for the time and then race to click and grab the coupon. They made it worse by introducing things like:

1. Reduced the limit from $600 to $300 annually.
2. Suspending your account for every possible thing (even if you open the site in different browser or different machine or different location).
3. Restricting your payment mode.
4. Delaying the payout by extending the original payout date.
5. Cancelling check after the payout.
6. Asking you for your legal documents and violating your privacy (these guys sell your information out).
I wish ebates or similar sites start better service than this.
