I just thought of a way to make money that I would like to share with everyone. In the past, I have been a plasma donator. It is similar to donating blood, but the plasma is extracted and the blood is then returned to your body. There is usually no light-headedness after donating, so it is just a commitment of your time.
I donated at a facility called CSL Plasma. They have locations in several states. I guess you could Google for something in your area. Right now, CSL is paying $50 for the first 5 donations. You can donate at least twice/week. After the first 5 donations they usually drop down to about $35 each.
Take a book because there is usually a wait.
