These people are mean spirited scammers. Their shell game of payout amounts is designed to mess up your donation schedule so you almost always receive the minimum. Obviously the compensation system is designed to trip you up and keep you guessing, so that desperate people will end up keeping on feeding the Vampire that is biolife.

You have to donate twice in one week to get more than gas money, but you can’t donate sooner than two days in a row. That means you only get one or two days to donate and if you miss it, the payment schedule starts over. You’d have to be unemployed to meet that schedule. Normal people’s schedule varies and they know you’ll miss a beat.

Some coupons amounts aren’t applied until your 6th donation, but you must make that 6th donation within 34 days. But you can only donate twice a week. That means If you miss more than 2 donations in the month, the clock starts over.

Then they offer you coupons that don’t apply until you have donated 6 times! If they apply that coupon, it will eliminate the previous coupon which hasn’t expired, so you will lose that money and won’t get paid for another month with the new coupon. If you ask what the payment will be for your donation that day they tell you nobody knows, you can find out after you donate.

Recently they have implemented a scheduling system to make things easier for nobody. In a city with 4 million people you have a 5 minute window to make your appointment. If you’re early and no one is in line ahead of you, you’ll still have to wait. If you’re late, come back tomorrow. If that ruins your payment schedule that’ll make them even happier.

Not worth the risk.
Not worth the time.
Not worth the discomfort.
Not worth the unknown factors.
Not worth the lack of decent compensation.
