I tried calling them at least 6 times. Always got an answering machine. Didn't leave a message after the first one, but went ahead and ordered on-line Tuesday evening, using the comment block to quote the discount information. Paypay notified me almost immediately that I was billed the full amount. A short time later I got a shipping notice. I figured I would NEVER get the discount. WRONG. The next day I got an e-mail telling me of the rebate. Around 5PM on Wed, I got a call back from the orginal message left 6 days earlier. Today, the product arrived. So, order placed on-line Tuesday night. Rebate notice received Wed. Call back received Wed. Product received Friday. Not bad at all. Haven't had a chance to even open the box.
