How about Target Gift Cards! Scott's Website has almost become nothing but the "Target Giftcard" site. The link below shows over 350 Target Giftcards!

I also have around 2000 - 3000 phone cards to go with the other plastic cards I collect.

I also collect all the "fake" credit cards that companies send me also!

Oh and AOL CD's (anyone else have a copy of AOL 1.0 on disk )
