What is the reason behind the popularity of auctions among consumers?

What will be an ideal response?

No one has quite been able to come up with any single reason as to why auctions have become so popular for consumers. Some possible explanations would include the chance of getting a really good deal, the fact that buyers are able to set the price, the sheer thrill of winning, and the competitive challenge involved. If auctions in general lead to higher-than-average prices, sellers are also interested.
