A "40% discount" means that the price of an item is reduced by 40% from its original price. For example, if a shirt costs $50, a 40% discount would lower the price by $20, making the final cost $30. This type of discount is often used in sales to encourage customers to buy products. Discounts like this are common in retail stores and online shopping platforms. They can apply to various items, including clothing, electronics, and household goods. Shoppers often look for discounts to save money while purchasing the items they want or need.
