If you happen to have an Office Max in your town they have an in store only offer that can't be beat. Buy a bulk pack of 100 CD-R’s for $19.99 and receive a $20.00 mail in rebate. Your only going to pay the cost of sales tax plus the price of a stamp. (here in Texas it works out to .02 cents per CD.)
I think the offer ends in a day or two.
