Several years ago, Marvel reprinted Golden Age Captain America 1-10 in two volumes, which went out of print pretty quickly.
I got volume 2 about a year ago, because it's in less demand but Vol 1 is very, very pricey. New copies of the paperback edition run at least $70, and over $100 is not uncommon.
I happened to be looking for it at half.com about a week ago, and someone had one listed Like New for $29.99 so I jumped all over it.
It came today. It's pristine. It looks unread, and there's no shelfwear. It was in shrinkwrap, which may or may not be factory.
Take that Hitler!
