I tried the Staples $10 off $20 coupon at two OfficeMaxs and was shot down both times. They would accept a Staples coupon except for the part about it's having to apply to Staples items only--they said it would only apply to OfficeMax brand stuff. (Got some Staples CD-RW's, tape, and letter trays with one that I downloaded via a FatWallet link a couple days back.)
I did decide to get the HP (allegedly Lite-On) drive. If I can get the rebate, it will be a steal. Otherwise it's a rip-off. Can't ever have enough decent CD-RW drives for $12 round trip ($9 after rebate plus sales tax plus $0.50 for stamps and an envelop). It would be nice to have an extra for when my current CD-RW dies or for when I build another computer. (It's a "Micro Advantage" 52x-32x-52x drive that I got from OfficeMax last year, also for $40 - $30 rebate. I did get the rebate. Turned out to be a BTC Technologies drive, which is allegedly junky, but it's performed well so far.)
