Members can cash out there each time they have accumulated $10.00 in their earnings balance.
There are 3 options for cash out:
1. Amazon.com gift code. This is the option I always choose. They send the $10 gift code to your email. You can then enter the gift code into your Amazon account to use toward purchases at Amazon.
2. Dining Dough $25 gift certificate. I've never used this one. It can be used at various restaurants but best read their information before choosing it.
3. Payoneer. Prepaid master card.
I am mighty sure, the 2. one would not apply to you at all since you are in India.
Most the surveys at CSR are geared at those in the USA, UK, and Canada. Not sure how many or how often, if ever, members in India receive surveys. I will add that you can in fact earn affiliate earnings if you enroll active users.
