Online shopping is a form of electronic commerce which allows consumers to directly buy goods or services from a seller over the Internet using a web browser or a mobile app. Consumers find a product of interest by visiting the website of the retailer directly or by searching among alternative vendors using a shopping search engine, which displays the same product's availability and pricing at different e-retailers.

Online shopping or e-shopping is searching for and purchasing goods and services over the Internet through the use of a web browser. The main allure of online shopping is that consumers can find and purchase items they need (which are then shipped to their front door) without ever leaving the house.
