There are a lot of ways you can make money on the internet that are legitamate. These are not get rich quick sites and can take some time to build up some money but it's worth it in the long run.
The first site I joined and have been a memeber of since 1997 is www.Mypoints.com. It is a relatively simple site to do and obtain points from. You can receive points from receiving emails, purchasing things off the web, and answereing polls. If all you do is sign up for their emails you should be able to get a $25 gift card within a year.
I would recommend signing up for a free email account first, then you won't be bombarded with all the junk mail associated with the sign ups you'll do. Then sign up for mypoints.
If you send me your email I will send a referall email to you. You can also make points from your referrals.
