Well this issue has been resolved from a legal/financial side, but my previous comments of buyer beware still stand. There is some bad product mixed in with perfectly good stuff. Ask lots of questions if you feel the need to buy.
On a personal opinion note, as well as a "what is good for ICE and the "company" of ICE", I would request that you not buy from this dealer. While I think its very possible they did not know the materials were fraudulently taken for resale and should have been destroyed in the handover from Mjolnir back in 2010, you would have assumed that such a large and well spread stash would have elicited some questions. I think, morally, its wrong for these to be sold and if you want these products, you should buy them from RPGNow (though not all may be available at RPGNow and there may be good reasons for that!).
You will NOT be sending cash into ICE that will be plowed back into developing more product, but helping the chain that supports illegitimate supply. Think about it before you buy.
