LG DVD-R 16X Speed Discs - 150 Discs for $49 including shipping!
Personally, I don't buy much in the way of blank media, so I'm not 100% certain on the hottness of this deal, but I'll let you and the hot button decide.
You can get 150 blank DVD-Rs from TopBuy with the free shipping code linked below, for $49. This works out at under 33c per disc.
