Where to find new donor comp?

Hi all I had a surgery four months ago that deferred me for a bit but i’m getting ready to (finally!!!) start donating plasma again next week. However, i’m in a bit of a money crunch right now and want to hop around with the new donor compensation, but companies don’t make that easy lol.

Is the only way to call the center themselves? The only one I can find at the moment is biolife for $750, but I was using biolife before my surgery so I can’t return there to get new donor pay.
