Shopping cart system enables the consumer to perform eCommerce transactions and help them select the products out of the whole bunch of inventory, utilize the available deals from the shoppers, and make online purchases. A basic online shopping store has a selling flow where customer can add any number of products to their shopping cart or could store them in their wishlist for later purchase. At the checkout page, the online shopping cart system automatically calculates the discounted amount(if applicable), any coupon applied, taxes, and the shipping and handling charges of the package.
