Any inexpensive way to get a hard copy of this game if you already own the Impulse version?

I bought the downloaded version of the Ultimate Edition a while back when I thought that Twilight would never get a hard release (plus the fact it was part of some Impulse sale). However, I'm not exactly a fan of digital distribution and would rather have the retail versions of this game. Is there a way I can get the retail versions without having to pay full price for them?
