they could be MCC media, a spindle of 100 for $20 for the memorial day sale, as good as their Verbatim clearance price (every store has different price on clearance products, the price is depends on the store manager discrepancy so store mananger marks the down the price of clearance and thus not nationwide price). The last time I was at office depot I spot all the MCC media, you can clearly see the serial number ending with ******DVR** something like that, search for another thread for how to spot MCC media.
dont forget to check out the maxell CD-R too, see link above, 50 disc spindle for $5.99
LG External DVD burner, $39.99 on the last page of the ads
And dont forget to visit the clearance section of the store if you are looking for Verbatim 16X +R/-R, inkjet printable media, +R DL, all of them are on clearance, price varies store by store like I mentioned above.
