I tried searching the HDFC Pension Super, but not able to find on their website, wondering are they selling it?

First understand - How does the pension plan work?
The pension plan works in 2 phases which are:
Accumulation Phase: during this phase you pay your premiums and accumulate savings for your retirement.
Payout Phase: during this phase you start receiving pension from the accumulated value.

In Accumulation Phase, you invest in various assets like - MFs, Gold, Property, FDs, Business etc and create a corpus. And later on buy annuity, which will pay you back as monthly amount.

As mentioned above there is no need to buy the pension plan because word pension word is attached to it. Start investing in all the assets to create good corpus, because you never know which asset class will perform and depending on your risk taking capacity.
