I did a quick search and didn't find anything, so I figured I'd ask here. Does PF have an amazon referral link? If not, the admins should consider implementing it. Basically if someone here is to purchase a textbook linked here from amazon, the buyer pays the same price, but PF receives a small portion of the sale. I know a few forums that have this set up. The money could go to server costs or funding some sort of programs. Thoughts?
