Gangster Greed is a GPT (get-paid-to) site where you earn cash for completing offers and surveys. The payout for each offer is not as much as some of the places I work, but there is an advantage to working at GangsterGreed: once your balance reaches $10, you can cash out and get paid within 24 hours - usually, it's within just a few hours!
Toward the end of the week, we start to get a little strapped for cash, and places like this come in handy when we need a few groceries, a couple gallons of gas, a few packs of cigarettes or whatever to get us through till payday.
If you sign up for this site, make sure when you click on the offers that it takes you to the right place. I have noticed that some of the offers are also expired. However, the approval rate is very good; better than some other places I've worked. They also offer 20% first level referral commission and 5% for second level. There's also a very helpful forum. So yes, I do recommend GangsterGreed. It's worth it just to make an extra $10 to get you through the week.
