Even if I could, I wouldn't because I absolutely do not like medical needles at all.

Didn't they used to pay people for plasma? Has that gone away or have the rates not caught up to inflation?

Incentivise it

Pay them for it. How much does one get billed for a pint of blood?

Hmm let's see. I constantly get harassed multiple times a day to do it. Even though I'm underweight and can't donate. Ive told them this. Even when I met the weight requirement donating only caused me trouble. Last 2 times I donated they had to hold the needle in my arm because their phlebotomist suck. If I had not gotten a full unit they would have thrown it out. Im not going through a ton of effort to throw it out.

On top of that, the time before that they sent me to the ER because I was still lightheaded and couldn't stand after waiting an hour. I got to pay an ER and ambulance bill for the privelege of giving my blood away for free. Its not surprising ive soured on the idea. Donaters take on all the risk in our for profit system and get none of the profit.
