I got the $30 rebate, though it took a over 2 months, nearly 3. I did have to raise you know what to get my rebates on the *free* case I bought though. Three $20 rebates for a lousey "free" Soyo case with poor airflow. It took from August until February to get them, but I got 'em. Frankly, I'm more upset with the case than the wait for the rebates. Fortunately, it was nothing a Freezer 64 couldn't take care of.
Ever since Cyberrebate went belly up, I've learned to keep copies of my submissions, and keep buggin 'em until they pay up. So far, I haven't gotten stiffed yet, though Western Digital is trying my patience at the moment...
