Sorry to hear that. It looks like supplies are tight right now. I ordered mine from them on Black Friday (11/27/09) and got it twelve days later (12/9/09). I lucked out and snagged one from their 12/3/09 shipment.
This was my third iMac purchase from them and they've been good...
The only question you might ask is regarding the rebate mail-in expiration. Since it's not your fault that you haven't received your i5 in time to mail out the rebate claim, they should extend the deadline for you.
