As of 2015, BioLife Plasma Services offers a special coupon for people who have never donated before or donated more than six months ago, and those who use it get paid set bonus amounts for their first, second and third donations, reports the Biolife website. Donors are paid for each successful session in addition to these bonus amounts. Any coupons or promotions are advertised on the company's website and may change with time.
In addition to using this coupon to get bonus money for each of three successful donations, donors can also get bonus money if they are frequent donors, mentions The Atlantic. This offer doesn't require coupons but is agreed upon between BioLife and the donor.
