I redeemed 300 points (INR 300) in AIP Online Surveys for INR 300 Flipkart voucher. Got the voucher delivered to my mail id on 20 Aug 2016. Utilized the vouchers to buy a pack of 3 LED bulbs. Recently came to know that the balance unutilized amount can be used for later purchases, till the validity period ends.
As a proof please refer the screen shot below.
Thus we can earn small amounts from these surveys.
