Can I lower my maximum bid?
To lower your maximum bid, simply place a new bid. Your maximum bid will be automatically adjusted to this new lower amount.
Can I increase my maximum bid?
You may increase your maximum bid at any time by placing a new bid greater than the amount of your previous maximum bid. You will not be outbidding yourself by increasing your MaxBid.
For example: If your maximum bid is $50 but you are currently the highest bidder at $30, you may decide that you want to increase your maximum bid to $75 to prevent the possibility of being outbid at more than $50.
