Yeah, that's why I said, currently. And I'm sure Airtel will come up with lucrative plans not only for Multi-TV, but also for Primary.
Not charging NCF on secondary alone should be pretty much enough to provide the discount IMO. No need to absorb any channel cost discount. Need to do some calculations though. We all know TS is not that stupid to absorb so much cost themselves and benefit customers.
I read many posts in tata sky section that they r calculating multi tv cost slab only on basis of total pay channel subscription amount on primary stb, NCF isn't included for this purpose. It surprised me too.
