This is an advance notice. The sale doesn't start at Staples retail stores until Sunday morning, May 15. This price may or may not be available online, I don't know (you can check the website early Sunday).
$7.94 for a 50-pack of Staples-branded DVD+R and DVD-R.
According to videohelp.com reports 4x +R and -R, if you can still find them on the shelves, should be Optodisc. Questionable media, in my opinion.
8x -Rs should be CMCMAGAE1 or FUJIFILM03 made in Taiwan, while 8x +R should be MBIPG101R04 made in India. All three codes are decent quality media.
I plan to get a couple of 8x -R packs, hoping for CMCMAGAE1 which have handled themselves well in my burners so far.
