What is the difference between a 32bit/64bit OS and a 64bit OS?

Im looking into buying Windows 8.1, and it comes in these two versions.

The 32/64 is cheaper, but what one is better? What even is the 32/64bit one?

32/64bit has both installs.
The 64bit only has the 64bit install.

Where are you buying this from?

So I could just get the 32bit/64bit and select 64bit?

Yes. Get the 32/64bit Retail, and when you install, use the 64bit.
