well surplus computers are a reputable company, they've had many deals advertised on here. Normally i get an email with good deals, but missed this if they sent an email out about it. Found it while surfing their webpage. If i hadn't just bought 50 DVD+R disks from amazon, i would have jumped on the 100 packs of DVD+R.
But this is the cheapest i've found disks without any rebate hassles. Works out at 24cents a DVD, that's what i normally pay for branded CD-R's
