A maximum bid (or proxy bid) allows you to set a maximum price you are willing to pay for an item. Amplifyd's system will bid on your behalf in minimum increments until someone places a higher bid than your maximum.
Amplifyd pre-sets the bid increment and is the amount a proxy bid must increase. The system will place a new bid following the bid increment every time someone else places a higher bid than you and will continue to do that until the auction is over and you win or the price goes over your set maximum. You are notified by email if your maximum has been outbid and have the option to set a new maximum to continue participating in the auction.
Other bidders might also have maximum bids. You'll receive an email notification if someone else's maximum exceeds yours. Then, you can decide if you want to enter a new Maximum Bid.
If you enter a maximum bid and do not become the new highest bidder, another bidder has already entered a maximum bid higher than yours.
Your maximum bid is kept private from other bidders.
