I had already sent them a 2nd email last night telling them I will cancel the order if I do not hear from them by the end of the week. It's strange. I ordered a VF-1S from them a few months ago and that shipped really fast. This time around, I ordered a couple of small Gundam action figures. Perhaps it is not in stock and they are searching their "inventory" as you mentioned.
On a side note, is HobbyLink a better place to buy stuff from?
