I got about the same deal from TD, took forever and a day for the rebate to come, but they did come eventually. This deal comes with not one, but two rebates.
I also had to resubmit two out of three rebates after sending three rebates in one envelope (one was entered into the online system, the other two were not.) I resubmitted the two (in the same envelope) and both went through this time. All rebates were paid weeks after they were due. Actually not the worst rebate experience I've had (cough.. Mad Dog.. cough) FWIW, YMMV. On the plus side, shipping was fast and the packaging was very good.
I think I would try to find a board with PCI-E video instead of AGP. cost is nearly the same, and I think PCI-E offers more 'recycling' potential in the future.
If you do go the rebate route, be double-sure to copy your documentation, having those copies saved me $140. Don't waste your money on certified mail to satisfy the conditions of the "Tiger Direct Rebate Guarantee", since the rebate processor you'll be dealing with (onRebate.com) is a subsidiary of Tiger Direct. If they choose not to pay your rebate there is hardly any chance Tiger will. Do check your rebate's online status to make sure they've received your submission, and use the money you saved not getting certified mail to resubmit when they don't show up.
