A more thorough explanation:

Definition: Chilling a sale is when a group of people work together to discourage others from buying an item so that they can buy it themselves for a lower price.

Example: At an auction, a group of bidders might work together to intimidate other bidders or make them think the item is not worth the price. This way, they can buy the item for a lower price than they would have if there was more competition.

Explanation: Chilling a sale is a form of collusion where people work together to manipulate the market and get a better deal for themselves. In the example given, the bidders are using intimidation tactics to discourage others from bidding, which is unfair and unethical. This practice is illegal in many countries and can result in fines or even jail time.
