I know ZX told me they run into the same thing. The other vendors don't like them selling stuff cheaper than them so they try to get the promoter to drop them from the shows.Just an fyi. I asked about this subject before at many of shows in the area, and the most popular reply was, they were blackballed. They would show up, buy multiple tables and beat everyone's prices by significant margins. Did it enough to **** off all the other sellers.
