Yeah, those ain't gonna be cheap. Figure them at $50 and $100, unless the media hype pushes them more.
The custom covers are going to be impossible. They didn't describe how they are going to be different than other custom cover sets but for Amazing Spider-Man #666 there were pretty hard to get.
I'm thinking they will be photo covers celebrating marriage equality, individually printed? LOL we should send in this gem and order a bunch of copies as a gag.
