True or False: A person bidding on goods can change their bid after the auctioneer's announcement.

In auction practices, once a bid has been placed and the auctioneer has announced it as the current highest bid, that bid is typically considered final and binding. The fundamental principle behind auctions is to maintain an orderly process where each bid stands on its own until a higher bid is made or the auction closes. Allowing bidders to change their bids after an announcement could create confusion and disrupt the auction's integrity. It is essential for every bidder to be confident that, once they have made their bid, it is secure unless a new, higher bid is placed by someone else. This rule upholds the fairness and transparency that are critical in auction environments.
