I found a site that you can earn some extra money on. But - It's kinda wierd. I started it 2 months ago, and just got my first check last week. I didn't want to post about it until the check cleared.
You get money for doing surveys and offers. Some of the surveys are not "real" surveys, but if you just keep clicking no to all the offers you do get through it. They also give you money for signing up for things like ebay, efax, stuff like that. Most of them are free trials, so you can cancel before you get charged. But you have to be careful, there are some that you will get charged.
