I sent mine in the first week of March, Rapid rebates 3 weeks later said it had been received. Since then no rebate check has arrived and emails to them have been silent. Others I've talked to who put in for the rebate at the same time seem to have the same issue.

UPDATE: 5/18- Received mine today! So they're running on the end of the 10 weeks estimated time. Either way Century still lived up to the money back.

There's another thread discussing this, and those guys are still waiting too.

I have a feeling the rebates won't go out until next quarter, so JUL, since they wrap up in AUG.
