First of all i would like to say it is not a profitable market place. It is just a way where students can fine to buy 2nd hand book.
I have already told that they could negotiate through
online chat or by the cell phone 
.
For sellers, DIU market place wiil be a smart way to sell their books in a smart negotiation. Sometimes we do not have enough time
to go to Nilkhet to sell the 2nd hand books and also carry such a huge books togather. So DIU market place is a smart place to sell them.
After better negotiation with the buyer, he could bring it during the class day and i think it is also a good way make good relationship with
other students beyound the only class room students. And i want u to make statistic that most of the students in your class have not sell their previous
semester books only because of do not have time to go to Nilkhet to sell it or did not fine a smart way to sell other junior DIU stunents because of
lack of communicaton or a smart way.
Secondly, in here there will be lots of post for the same books with different prices. So they will be able to campare those
prices and also able to get a good idea about what will be the effective price. In addition, before they buy the book at the
begining of semester they will do search in the market place due to get price idea and i think it is a great promotion for them
and it is also a great idea to buy 2nd hand book rather than but a new book.
