E-Commerce on books

In this website we can buy and sell the books.
This is an e-commerce website that helps the students buy books not only from the vendors but also from other students.
In this we have different types of categories like academic books, comics, novels etc.
There are two logins, one for the seller who wants to sell the books and can also upload pics of the books. The other login is for the buyer who can see the details of the book and contact the seller for buying it.
