Coupon codes are a type of code, which consists of some letter or numbers. Entering these letters or numbers into the promotional box on the shopping cart checkout page, customers get to know about the discount on their purchase. Nowadays, online merchants have started offering coupon codes to their shoppers to establish a friendly bond with them. This approach is beneficial for the retailers (they get discounts) as well as the customers (they attract more customers). The coupons are easy to use and perfect for people who love doing tons of online shopping.
