I have used OLX.in for selling out some of my old books and I am quite satisfied with the service.
The site is also good for selling cars, bikes, etc.
I received several responses for the ads that I had placed.
Also, the best part with services like this is that only persons who are really interested in buying the things contact you.
The site’s layout is simple and easy to work on.
Also, the site’s load time is really fast.
