Frankthedm: That and he doesn't like to leave feedback for his customers. I feel that feedback works both ways. I, as a seller, like to leave feedback for my customers and expect the same. The same deal applies when I buy stuff as well.
It's a surprising # of feedback that notes that stuff that was bid on was suspiciously in a later auction. Seedy stuff there. Avoid someone like that. Unless they obviously are an online version of their brick and mortar store. There are a few sellers of miniatures that I can tell they're also a store that sell multiple copies of minis. That goes for some sellers who sell gaming books as well. This guy makes you really feel like "buyer beware".
