Absolutely. The last 10 times our so that I've donated they were fully booked.
I would recommend calling if you haven't made an appointment.
They want your blood. They prefer an appointment but I'm sure they will take a walk in
Actually yes you do need an appointment. No walk-in
I don't think you NEED an appointment but you might not get lucky with walking in. Since most people book ahead of time they might not be able to accommodate beforehand. You could try you luck
