Darn, I found out about this after they stopped doing them. 
Huh? They still are doing it. Follow the link and you can purchase the pdfs they have up.
New classic D&D PDFs are added to www.dndclassics.com (as well as www.drivethrurpg.com and www.rpgnow.com) every Tuesday. This week's additions include products from 2nd Edition, 3.5, and 4th Edition (including the first two D&D Encounters adventures).
Hope this helps! :D
Anybody know when they'll put the Mystara Gazetteers on dndclassics.com?
Sorry for the totaly vague post. 
What I was bummed about was that they stopped doing the articles about the up and comming releases for the next week. They did one on 9/30/2013 and the last one on 10/7/2013. I guess they did not get enough people checking out the articles to continue doing them. I thought the articals were great. 
They have stopped doing a lot of things lately
