If the rebate doesn't come within the stated time frame. Give the company a call/email. They usually have a rebate department that deals with this. I've had many encounters of slow/delayed rebates. I just type an email/talk to the customer representatives about it then they usually mail the rebate in through express or something. One encounter I had was when OCZ mailed me two rebate cheques so basically i got the ram for free plus extra money.
