This may not be the best place to post this, but I saw this rack at Best Buy yesterday that holds and displays pens. What caught my attention is that they are sized perfectly to put 2.5" x 3.5" trading cards into them laying flat, plus they have a place where you could stick labels on them to organize your various series. Something like this would be an immense help to me with all of these new series we've had since 2004. It's a great way to store your extras and not have to go digging through closets for them.
The question is, how to get our hands on them. They are obviously not for sale at Best Buy.
