Okay, so basing off of some earlier coupon codes for the Tamil & Telugu Yearly plans that were available when I susbcribed to Aha 3 months back, I was making up random coupon codes and tried to apply them. One of the codes that I tried worked!
It looks like there is a Rs.100 OFF coupon code for the Gold Plan right now.
I will hold off until tomorrow to see if any of our members here have a referral code (that way both of us will gain something). If not, I will use the above coupon and subscribe the Gold Plan (4K Streaming).
