For example – If A places a bid at $2 and no one else place a bid on the same amount, it is considered as a unique bid and A will win. If B places a bid on the same item at $2, then it will be categorized as non-unique and none of them wins the auction. It is necessary for B to place bid more than $2 in order to win the auction.
For example: The starting bid for an item is $5. A is the high bidder to place a maximum bid of $6 on this item. His maximum bid of $20 which will be kept confidential from other members. B places a bid of $7 and becomes the highest bidder. Automatically A’s bid is raised to $8 outbidding B at $7. It will continue till the time any buyer crosses $20. It is the limit set by $A which is only known to him. If nobody crosses $20, then A is the winner. If anyone crosses $20, A will receive a mail to increase its limit.
