I have used Quikr.com manly for selling books.
The site’s design is fairly simple and easily navigable(although a bit crowded with other elements).
Also, the service is really helpful for selling out things like books and mobile phones, and even properties.
I received a fairly good amount of responses for my ads.
Also, the site’s chat feature(Quikr Nxt) comes in handy for contacting the sellers or buyers.
