I made a snapshot of my vps and it was one click and started, I assumed it was free. I read in to a little more and there is a small charge, and I'm not complaining the price is more than reasonable for what it is.
It's just more the fact that I didn't actually know that there was one, people shouldn't need to read up on the documentation in a blog post to know how much something costs.
Other than that, the service is great.
