PG-HQ Forums

I'm just a newbie but I didn't have any luck searching the forum for information on this subject.
I'm a Gold Club member and have downloaded all the free .pdfs. I was going through game catalog and noticed some that are Type listed as bound/pdf or book/pdf (airborne remastered, north wind, etc). How do I get a copy of the pdf? 
Thanks

Avalanche Press used to sell PDFs of some of the supplements that were scenarios-only. I think the practice was discontinued about 5 years ago.
