A "mega sale" is a large-scale promotional event where retailers offer significant discounts on a wide range of products. These sales often occur during special occasions, such as holidays or seasonal changes, and can attract many customers looking for bargains. Retailers may advertise these events through various channels, including social media, email newsletters, and in-store signage. During a mega sale, shoppers can find deals on items like clothing, electronics, and home goods. Popular retailers, such as Amazon and Walmart, frequently participate in mega sales to boost sales and clear out inventory. Customers often plan their shopping around these events to maximize savings.
