I'm a long time NAPP member. The membership fee here in the US is just $99 for a year. Though you can't pay monthly, that's only $8.25 a month. The Photoshop tutorial site Lynda.com is $25 a month or $250 a year.
PM me if you have any more questions.
Here is my referral link:

You don't have to be a pro to have savings equal to or greater than the yearly membership fee.
For your $99 you get accesss to the members web site, help desk, forums where many certified Photoshop experts give advice, and 100's of tutorials.
You get 8 issues a year of Photoshop User magazine, that also has a large section devoted to Lightroom articles. It has regular sections on image presentation, and legal issues.
NAPP members get discounts on hardware, software, travel, lodging, car rentals, lens rentals, it's an impressive list.
As an example, NAPP members get free regular UPS shipping on everything we buy from
B&H Photo Video. Last year I saved over $500 just in shipping charges from
B&H. I have mentioned several times here at TPF that as a NAPP member I don't have to pay the shipping charges on 9 foot long rolls of seamless background paper.
NAPP members get a 15% discount on Adobe products.
