There was no buyer's premium for Bo Whoop. I spoke just now with the seller's friend who shipped the gun to Julia's. He had spoken with the owner this afternoon after the sale, who was still distraught at having had to sell it. Seems that the reality of it being gone actually sunk in when they got the word from the auction that it was really sold, and my friend said he was "almost in tears". Medical bills required the gun to be sold. However, he said that Julia waved the commission on Bo Whoop, a practice that he often does when there is a very desirable piece that "leads" the auction.
