My thesis subject is titled "An E-Commerce Website (Business to Customer B2C)." A B2C Ecommerce B2C marketing refers to a corporation's approaches and procedures for advertising its products and services to individual customers to utilize in their everyday lives. I'm constructing this web application with the MERN stack (MongoDB, Express, React, Node) and PayPal for online payment, so users may pay with their PayPal account. This online store has the features where a user can add or remove items from the cart. User will need to go through email and password authentication to proceed to checkout. Once the order is placed and paid user can see all the details including shipping address, payment method, cart items and quantity of cart items.
