I have some other sites with a fair number of uniques that I've never been able to make anything off of (well, no more than a couple dollars).
For any site, though, the amount of money you make per visitor will have a direct correlation to how related the search term the visitor comes in by (presuming search engine traffic) is to the item you're hoping to get the person to buy. If you look at your counter/tracker/logs and see what search terms people are coming in by, that'll give you an idea of the affiliate programs you should look to sign up with. Likewise, if you can do so while making it flow naturally, you might want to change the text of your pages a little to try to attract more profitable search terms. For example if you're hoping to get people to buy anime videos like someone further up in the thread suggested, it's best to find a natural way to mention terms that people looking to buy those would be searching for a few times in your text so that search engines will see it.
You make that kind of money from refferals?
