Ok, let's say I give you some gold bars. You collect them, transport and store them, then give them away free to thousands of others that need them.

And yes, it's still a markup. From zero to whatever it sells for.
I think you're missing the point. If they wanna make a profit offa blood sales I got no problem with that at all. But they prey on gullible people by making it sound like it's all some kinda non-profit charity. It's deceptive.
