👉 An auction weapon is a strategic tool used in online auctions, particularly in competitive bidding scenarios, where the highest bidder wins an item but pays the price of the second-highest bid. This mechanism incentivizes bidders to outbid each other aggressively, knowing they only pay the amount above the second-highest offer, which can significantly reduce their overall cost. Auction weapons like "bid stacking" or "bid doubling" amplify this effect, allowing bidders to increase their chances of winning at a lower price by strategically raising bids in response to others' offers.
