I use CashCrate.com, I usually make a good pot of money from this site a month, it's not a goldmine but it's a huge help to me, especially being in college. This site is honest to goodness my favorite site to make money on because it's simple, easy and you actually make money. When I first joined the online cash sites I'd do the offers but were never paid or the sites would find every excuse not to pay me. So I stick to cashcrate since it's a trusted site. Good luck and happy money growing.
Tip: If you do sign up, they give you $1
.25 for filling out your profile
.10 for making 10 searches in their search engine
.03 for checking in for the day
that's $1.38 already! it's not alot but it took less then 10 minutes to get. =)
From there you can do the offers, daily surveys, play games to get points, the cash tasks, and alot more. Also try to get referrals, I use to host Online Money Meets in my dorm or coffee shops and got alot of referrals that way. There's other tips and tricks you can do to make more money which you pick up as go along. And if you can't get referrals trust me I know it's hard, there's still lots of way to make money with CC! =D
