Well, I'm gonna have to look a little harder to find the Gun X Sword box set i guess.
to the best of my knowledge, Gun X Sword hasn't gotten a collected dvd release here in the states yet.
Nor will it ever, most likely. It finished on DVD May 2007, and Geneon died only ~6 months later, so there was no time to do a set.
So the only legitimate GxS R1 release is in singles format (7 of them). TRSI has all but 7 in stock, but with the Geneon sale over they're nearly full price. Weren't they eligible in the $5/10/15 sale? If so,
that would have been the time to grab em. But you should still be able to find all the discs, depending on how much you want to spend.
