If you don't have any money, that's okay! Just pay what you can afford. At $5 per month, that's about the cost of a few cups of coffee at Starbucks. And this is your education that you're supporting. I'd say, "What a good deal!"

The more money the website collects in subscriber fees, the more time your teacher can spend working on this website and other websites in the future. So, put the guy to work already!
