I doubt it too. They'll want to recoup some costs, and I'm guessing they're figuring that most people who sent prints back won't be ordering again anyway, and those who still will order weren't really worried about the signatures -- or don't know about them -- and will continue to order at the same price.
That said, it's a really nice looking print. I'm sure the colours will pop quite a bit with her! It'll be interesting to see how fast she goes, as she's a pretty significant comic character to X-Men fans. I mean, after a controversy like they had, this is probably one of the best prints to test the waters with! It has all the markings of a print that'll be fast to sell out, other than being done by Artgerm.
