When I completed my intermediate then I have joined in narayana juniour college for IIT coaching, for iit books I went to koti, my seniour suggested me to go for univercell there I will find each and every books.
So I directly went there and I have asked them they gave me all the books which I have asked. Each any every book is available. And they gave some discount for me.
Because of money problem I asked them to give second hand books. Here they will accept the books if they are good. If the book is second handed they will give 30% discount nearly. But for this store we have to go koti, if they extend their stores that would be good.
