Common questions about bidding in IronPlanet auctions How does the bidding work in a sample auction? Why do I immediately get outbid after placing a bid? Why does the bid jump so quickly? Can I increase my maximum bid amount? Is it possible to bid against myself? Can I retract or decrease a bid? Do I have to bid in whole increments? What happens if two maximum bids tie? Can I bid during preview? When is an auction extended? How can I tell if I'm winning an auction?
