kong,
congrats on being nicotine free, it's a huge accomplishment no matter how you got there. Like the rest here, I believe that committing to being an active member here is the single best thing you could do for your quit.
To answer your original question:
use this link to get the discount: https://apfco.com/secure/w1370/index.cfm?fromktc=Y
I'm backing 30 on this. The point is, the moral door opener to the site is participation. I can't say this for fact, but I'm pretty sure it would be considered that you are a member of the site to receive any "goodies" and the fee of membership is participation, if only roll.
Morally, I don't think any of of long term guys would care if you get the discount, our fight is with the nicotine, but the new guys are supporting the site in a fair manner on this.
Why should you get a goodie of the site if you are not really a member?
Congratulations on your quit.
