One really great thing about this site is that you can ask questions in the forum about anything on or related to teaching material contained herein (including songs lessons) , and you'll get a timely direct answer from a bona fide professional musician. That alone is worth $99 USD** per year (30 cents/day). And even after the purge, there's still way more than a lifetime worth of songs to learn. And let's not forget Anders' Guitar Insider. Some of those tips and tricks are truly priceless.
** I'm not sure what that amounts to in Canadian currency - something like 4 beaver pelts and a fistful of moose teeth 😄
