Which one is more cost effective?

I'm doing Runespan, currently have level 3 Esteem or whatever. I want to buy level 1. I could either buy level 2, then level 1, or just level 1. Which one would be more cost effective?

Please only reply if you've done it before and know what the price drops down to.

It's exactly the same cost, whether you buy them at the same time or not.
