If you get a Gamefly free trial, can you cancel right after it's over?

Or do you have to continue paying at least for a month. Apparently, there is a 10-day free trial, and I'm really tempted to try it. But the site says you have to pay $22.95 thereafter.

 So does anyone know?

If not, then I'll just get the $8.95 for just one month, because I don't want to spend too much money. I can cancel the account any time I want, right?
