my bf used to sell plasma sometimes at the zlb here and the first time he went in he got 40 bucks and after that 20 bucks. they pay dependant on weight, you can donate 3 times a week. also, they do a whole physical and std test the first time you go in, so be prepared for a like four hour ordeal. but if you don't like needles, don't do it! if you freak out they never let you back in.
