To all new-comers to the auction tomorrow:
Be cautious about waving to anyone once the auction starts, or just waving your arms in general. You might end up with an unexpected purchase...I speak from experience. It was a funny way to learn about auction etiquette.

funny you say that as I always pay attention to the auctioneer when I put my arms behind my head. I wanna make sure he doesn't think I'm bidding
