I wondered that too. From the forum rules (the link is just below the forum title - if you've never noticed it):

"Members may offer items of their own survival gear that is surplus to their needs for sale on a non-commercial basis, but members should be advised that they purchase such items at their own risk and to be sure to take whatever precautions they feel may be appropriate as we cannot and will not get involved in the transaction other than to provide a means of communication. Purchase at your own risk."

I would suspect that a sale of items on the 1st or 2nd post in this forum would still be frowned upon.

So clean out those closets!!

BTW, I've always thought that pics of high-quality, but "deflated" packs look so very sad. It makes me appreciate the art/science of making commerical-quality catalog-type pics.
