Went to an auction with 600 signs the other day. There were about a hundred or more live bidders and it was on Proxibid as well. I left after two hours and I bought one sign. I had had enough of the craziness. There were many fake signs mixed in and it was clear many of the bidders could not tell the difference. My advice go to the shows and buy retail, it's cheaper. {ten hours of driving in bad conditions, a night in a hotel ,gas , food for one sign}
