Offers are only for United States, Canada, UK and Australian residents. However, if you are not from any of these countries you can still earn points and claim prizes. Please see the referral page on how to earn points.
It sounds to me that as long as you earn Referral Points, you can get your items shipped to you in India. However, you cannot complete offers to earn points. I hope that cleared up some confusion.
Please feel free to correct me if I'm wrong.
