Hii all,
I recently listed some old mobile and PC monitor and hence i would like to comment on this topic.
I was never charged anything as many think.
List for 7 days-Its free
add ur(icici,hdfc,etc) bank account for paisa pay-its free
do not go for bold or any decorated listings-they charge for this.
else everything else is free..You can certainly try selling your product.
there are many more sites like ebay (for eg freefew.co.cc,indiatimes auction,rediffauction,auction.com,etc) but ebay is one of the best as far as my experience goes.
All the best
