I had to look up the term, and yep... that's "ringing!"
The couple auction houses on the regional circuit I hit up with these guys don't seem to pay it much mind. Maybe it's due to the business we bring at/to their auctions, maybe it's due to the horse trading we conduct with these guys out of auction, but either way, it works for us.
Now, with that in mind, there are other auction houses that get pissed if their customers so much as conduct business with each other after the auction. I guess the trick is knowing how each auction goes about their business, as each is different.
As far as those couple who do tolerate "ringing," there's still no accounting for the loose cannon "X" factor who will pay whatever they have to if something is purdy and shiny enough.
