Why are users outbidding themselves?
When a bid is placed, this is the maximum amount a person is willing to bid for the product. Our system will then automatically bid on behalf of the bidder, incrementally increasing the bid up to the maximum to maintain their position as the highest bidder.
When there is an icon indicating 'Automatic Bid', it means our system is actively placing bids for the bidder based on their maximum bid. This may appear as if bidders are outbidding themselves, but it's simply a result of the system updating the bid to reflect the bidders maximum limit.
