Inbox dollars is another place to make as much money as you have time/desire to. You can make money here by opening paid emails, taking surveys, completing simple tasks, playing games, and using coupons. The coupons are free, so you are getting the coupons full value, and 10 cents more, which is a pretty decent deal. Personally, I just cashed out my first check from here for 30 dollars (minimum), the delivery was prompt and our account is usually credited for your tasks pretty quickly.

Ways to make money on Inbox Dollars:
Paid Email- few cents an email, only takes a second or two to do
Playing Games- This is where the money is lilkely to be made through this program, if you can find a game that you are relatively good at, and become REALLY good at it, it is possible to make 20, 30 dollars a day on this website. I personally play "Wheel of Fortune" and pick up almost 3 dollars a game I win, while spending maybe 4 to 5 minutes playing it.
Completing Offers- Another way to make a good deal of money, while putting nothing in. However, you really need to be on top of your game for this one. You will accept offers to try the free trials of these websites/programs. It will ask for your credit card, and inform you that if you don't cancel within X days, you will be charged. As long as you keep a list of what you need to cancel, you will never spend a cent doing this, and will make between 1-10 dollars an offer.
Random Tasks - I do not recommend doing the tasks, they are horribly boring and pay almost nothing. But if you have the ability to complete this kind of work, there is money to be made.
Surveys- 50 cents a piece, and usually take ~10 minutes, not horrible, but again, most people don't have the mindset to be able to do this.
