If you click any link amazon puts a cookie on your browser that lasts for 24 hours. As long as you have that cookie and buy something from amazon I get a small commission on each purchase. It won't make the product more expensive. It's simply revenue for FJ.
So just click a link and buy from amazon.
. Why should I do this for you, you fat korean dictator?
1) It prevents me from using annoying pop-up ads that might contain malware but use friendly amazon text links instead.
2) Gives me money to pay highly skilled developers to work on the site, i.e. develop mobile, more upload features, etc.
3) Money allows me time to work on other sites (game review site I'm making) and research and learn about new technologies to make FJ faster, easier to use, and increase my linux skills.
What if i'm not in the USA? Do you still get commission?
