The 3 licenses is the family pack with Home Basic or at best home premium, which are, in my eyes, not worth the hassle of getting.
Try and get an OEM License, these should be MUCH cheaper. And if it's ultimate, even the language does not really matter, as you can install different languages later on.
And there are still 5 manipulator discounts
If you use Bitlocker or need 35 Languages to switch between....then get Ultimate..
If you only need the 35 Language support, get Professional
If you just want Windows 7 with the nice visual elements get Home Premium
If you just want Windows 7 without the visual effects get Basic
If you buy an OEM version, which I do NOT recommend, you will be limited on re-activations. The activation policy on OEM is now different than it was in the Windows XP days...besides...OEM is not any cheaper and has no benefits over Home Premium.
Home Premium is Ultimate without the language support or bitlocker. You dont want Bitlocker and 99% of people could care less about changing between 35 languages.
and if you cant get by in life without using a "five finger discount" i feel sorry for you
