How does templatemonster operate?

Hey guys, quick question (not sure where this goes, if this is in wrong section, please move, thanks.).

I was wandering how templatemonster.com operated.

When you purchase a template, do you get a DL link immediately? How are they able to control how many downloads are given out?

Basically, I want to know what happens from the time a template is purchased, to the time you set it up.

Thanks, any information would be great.
