Ask HN: Anyone making money from Allposters affiliates programme?

Hi,

I have a number of niche sites that attract a healthy amount of targeted traffic and send allposters a lot of unique visitors, but the conversion rate is extremely low.

Has anyone had any success with allposters.com affiliates? Any thoughts on how I could make these sites into money makers? If you want to check the site out : http://www.spanishcivilwarposters.com/ http://www.ww1posters.com/

I know they are not exactly oil paintings, but the bounce rate is lowish(50%).
