James,
I don't know if you know about
[Only registered and activated users can see links. Either login above or

Not sure if you can use both portals but just wanted to throw that out there! They give you 20 points per dollar good toward items from thier site. I usually opt for the $5.00 gift certificates to movies or restaurants just because I know they are good for lots!
NOTE: Don't know if you have dealt with outpost.com before but I purchased from them last week and they are pretty good, especially with the free shipping. Beware though that they will not pay for you to return the item should you not like it. You may want to take that into consideration before you buy. They had a 50 pack of CDR's for less than $10.00 if that interest you.
