The web is literally crawling with free Photoshop tutorials!

There are a lot of free tuts at Adobe. I'm not sure where you were going that you could only find tutorials you had to pay for, (I'm guessing Training,) but if you go
here you'll find the free ones.
There are also a number of sites that have vast numbers of tutorials. Try
PSLover.com eScrappers.comRussell Brown Or
Digital Media Designer, (which often takes you to the Creative Mac site, so don't be alarmed if you don't have a Mac,) where Dave Nagel has a whole series of Photoshop Tips for Beginners. (starting
here,
here for the second one,
here for 3,
here for 4.)
Those might not be exactly what you want, but Nagel's stuff is great, and his brushes are wonderful.

On all these sites, you'll want to search the vast tutorial base for whatever it is you are looking for. You might want to start with "Beginner" and go on from there as you develop specific questions. (The Digital Media Designer family of sites has a funky and weird search, that doesn't always work as expected, which is why I gave you those 4 links. So for that one, you might want to browse the Tutorial Archive.)
And, of course, if you have a specific question, you can ask it here.

NAAP is
very good, but, at about $100.00 US, I'm not sure I'd call the fee "small." On the other hand, if you're going to be buying stuff for your computer (software, hardware, or supplies,) or traveling, or something, you can easily recoup that in the course of a year by using the special discounts you get as a NAAP member from various retailers (like PC Mall, Apple, Dell, Office Depot, several Rental Car places, and lots more.)
I'm a member, and I love it, by the way.

Hope this helps!
