You need to shop around if you're interested. It can be benificial to look and call around. For example-Biolife here pays $20 for your first donation of the week and $50 for your second donation of the week. Right now the one in my area is doing a $50 your first 5 donation deal. Worth trying anyway. I end up with about $280 a month. Some areas pay less. But, here is the kicker, north and south of are centers who pays more for people who do their vaccination programs and mine does not. So if you're willing to be vaccinated for the hepatitis series they will pay extra as long as your antibodies are up. South of me they end up paying over $400 a month as long as your antibody levels stay high (everybody's body is different so don't plan on that happening.) But it's worth a shot if you don't mind a free vaccination! It's to far for me as I would spend more in gas and time than the extra is worth. My daughter in Boise says the center she goes to pays $35 for the first donation and $45 for the second. So... call around and ask.How much does biolife pay? I've heard of people doing it, figured it might be some easy money for tags, gas etc.
