Cashkaro - as it names creates cash after you spend on something which you need it with a discounted price. It is really good site, where you can grab some offers and get cash back. I really recommend it.
Suggest you to go through this site, nothing harm other than extra click but you will be lucky enough if you get a good deal.
Very easy to use and convenient also. Its not at all fake, I recently got 1000/- as cash back.
