Because they earn a certain amount if someone shops from their link.4 points=1Rupee you earn on Payback
I’d shopped a total amount of 1,25,000Rs through their site for which they told me I’ll get 87,000 Points. These points get approved after 2 months. So they told me to wait two months and after that I’ll get my points. After two months got over in December 2015 they refused to give me my points. They told again has taken back the points. Even though I had not returned any item.
