The event precedes Diwali and is one of Indias local retail sales holidays. The sale offers huge discounts on a range of products, including smartphones, laptops, accessories, clothes, and more. The deals offer 50 to 80 percent off on electronic accessories, tablets, and televisions, and other appliances, and you can also get 75 percent discounts on 4K TVs and refrigerators. The sale also offers a wide range of products at massive discounts, including ACs, printers, washing machines, mobile covers, screen guards, and more.
