need rebate help asap!

[whitak24]

i bought the 100 cd spindle at Circuit City awhile back. but i was lazy and didn't get around to sending in the rebates until now (one of them has to be postmarked by tomorrow).

anyway, both of the rebate forms ask for the Serial #.

however, i don't see a serial number anywhere (unless it is the number that is printed near the center of each CD-R) other than that, i see no numbers anywhere on the packaging or on the receipt.

what did everyone else put down for that?
