Since you live in the US, check your Sunday paper for the weekly ads from stores in your area. Office Depot, Office Max, Best Buy, Circuit City, Staples, and CompUSA have tons of rebates for dirt cheap media. Most of the time it's CMC, which I have had no problems with lately, but I think Best Buy has a deal on FujiFilm now, which is Taiyo (with the screw-top spindle).
