Cosmic Comics. Pretty good back issue selection, I usually stop by for Free Comic Day since they throw some of their overstock into the free comic pile.
There are a few trades (old Marvel stuff) that I would love to get, but I don't think I've ever paid full price for any of my books (and I've been collecting for many many years). When you say "hook up" is there a discount involved?
Because while I love collections of horrible Spidey stories, I can't pay $20 or $25 plus tax for them.
