How much glimmer can you buy daily at Tharsis Outpost?

I did not know about this until recently. It is located exactly on the opposite side of the enhancement core chests, where you can buy 40 cores per day for credits. I have too many credits clogging up my postmaster. I am reworking builds on all 3 toons, so using up a lot buying prisms. I am claiming 20,000 glimmer a day. I saw someone mention 40,000. What is the max daily amount?
