Well, as a follow up to my story:
The Dude and his two friends (in Japan) opened up 3 Master Cases between them. I thought I was getting one of the Master Cases they ordered and they were spiltting the other two, but that was not the case (obviously).
It sounds like what I got was 3 non-chase boxes (they opened the boxes to see which had the chase by the order of the individual boxes in the box of 12) and then one box that was re-assembled after the chases were pulled out. He feels bad about the situation and he still claims that it really was just a language barrier misunderstanding that led to me getting what I got.
Looking back through the e-mails, I did notice that the word "sealed" disappeared after the first few exchanges and his final message did say "factory master case". I guess I just assumed "factory master case" still meant "sealed master case" like it did earlier in the e-mails and not 4 searched boxes put back into the "factory master case" for shipping. Yeah, it's hard to believe but he claims that what he thought I really wanted was the Kubrick Cardboard Master Carton (like someone buys a master case from Asia just for the cardboard box
).
Regardless of whether I believe him or not, he isn't selling any of the chases on eBay and hasn't in the past for that matter. I've had a couple of other deals with him in the past for stuff (he got me an Eopie during Episode 1 and a few other HTF things for cost on two other occasions) and I have always been treated fairly by him on shipping costs and things like that in the past.
I'll just chalk it up to a bad case of buyer beware and I guess I avoid dealing with him in the future.
