A retailer or a shop is a business that presents a selection of goods and offers to trade or sell them to customers for money or other goods. Shopping is an activity in which a customer browses the available goods or services presented by one or more retailers with the intent to purchase a suitable selection of them. In some contexts it may be considered a leisure activity as well as an economic one. In modern days customer focus is more transferred towards online shopping; worldwide people order products from different regions and online retailers deliver their products to their homes, offices or wherever they want. The B2C (business to consumer) process has made it easy for consumers to select any product online from a retailer’s website.
