This Forum is for the promo that compusa is running for 19.95 for 100 blanks. I have bought a ton of them and work great. This is less than .20 a disk...the cheapest I have ever seen. I wanted to let everyone know its such a good deal. I do not work for compusa and are affilated to them in anwyay. Just want to spread a deal around. They are 4x rated, they do burn on 4x. They also work in most dvd players. Movies i make play in all my players.
