I said the same thing, and for a while was doing good reading what I already have, but that didn't last too long and I wound up buying some new things to add to the list. I'm going to try and hold off until Christmas though, I'll most likely get gift cards for Barnes and Noble from relatives, and that will go to new books, whether they are novels or graphic novels though I haven't decided, since there are a lot from both categories that I want.
In the meantime, I am back to reading what I already own.
Did you get the Superman/Doomsday DVD that came out? I haven't seen it yet and I am not sure if it is worth getting or not.
