A flash sale is a promotional event where products or services are offered at significantly reduced prices for a very short period, often just a few hours or days. These sales create a sense of urgency, encouraging customers to make quick purchasing decisions to take advantage of the limited-time offers. Retailers often use flash sales to clear out inventory or attract new customers. Typically advertised through online platforms, social media, or email newsletters, flash sales can feature a wide range of items, from clothing to electronics. Popular among both consumers and businesses, they can help boost sales and increase brand visibility in a competitive market.
