extending support period

I'm confused about extending the support period for my license. I have FlowHeater Designer 4.0.8.2 (64 bit) with updates through 3/27/2017. This is just a personal (individual) license. If I wanted to renew my support period in order to get the latest update now and into the future for 1 or 3 years, is the pricing the same as if I was starting from scratch? Meaning, is there reduced pricing for extending the update period compared to buying the product for the first time? And how would I go about that? The web site didn't seem clear on this point.

Thanks!
