Did it for a year about.
Depends on your weight, hence you are able to donate more, and resulting in the overall payment amount.
I was in the 20/25 or 25/30 range. The first amount of dollars is the first time in the week, the second is the second time. You can go twice within a seven day period an must be like 2 or 3 days in between your trips. The trip in the chair takes about 45minutes to an hour. You watch a movie or you read. The tests performed on you are 2, one is to check your protein or glucose level I believe, and the other is the amount of water or some @#%@. This is to check whether you may pass out or are healthy or some @#%@ like that. There was something else to see if you are in the 'do not donate' list as well. Drug test and drinking test are null. If you are dehydrated, they'll know.
There are good stickers, and bad stickers. Bad stickers suck as in it hurts, slight feeling, or they don't get the vein on the first ty and gotta re-stick same arm or other arm. Good stickers are in and out, painless like a small pinch and smooth. I drank a lot of water before going in, as waiting was like an hour, and then hour in the chair, so about 2 hours or more on a bad day, Good days result in 1.5 hours or less. There are days you know when to go in, like near the first of the month, when most people that do this get their government check
. You begin to get into a routine of knowing when to eat and drink to prepare for it.
The first time you go, gotta have like piece of mail with name and address or so like 2 pieces of identification. Then you get a 'physical', Its crap piss in cup and @#%@, I don't remember.
The one that I went to is called ZLB Plasma, but I think they are all 18 and older places.

I got a scar after having done it for like a little over a year, 2x a week. You end up looking like a drug fiend with elbow prick. You can do this more often than blood donations because you get back your blood cells in this setup. It is very safe as all needles and materials are sterile and packaged, and used onces of course.
Hope that helps. My way of looking at it was, I ate chipotle+a few glasses of water(-$6~) or chineselunchcombo(-$5~) to get +20 or so dollars for 2 hours, is an alright profit margin for time to sit and study/watchamovie.
