So how do I practice human manipulation? Where do I begin?

I mean, how do I get good IRL practice? I am pretty confident I am ready to start. My social skills are generally pretty good, not perfect, but decent.

If you are interested in getting free stuff, try SEing first things you actually own. This will get the paranoia out of the way and give you more confidence when talking to the reps. If you own some logitech products start from there.
