Christopher----Epson is offering free their $500 rebate on a 4900 printer and says not good with any other rebates or promotional offers. I think what the rep did was just give you the rebate coupon that is available to anyone to print out from the epson rebate website and like those, useable upon purchase of the printer.
I'm sure you're not aware of that as you wouldn't intentionally deceive anyone here, but please post a small resolution pic so we can see what it says, if you feel I'm incorrect. There is no question however, that Epson is offering anyone a $500 rebate on the 4900, 7900 and 9900 printers valid through the 3/31/2011. pdf attached below.
