Too Much Filament?

When you have a man cave with two Ultimakers you can not have too much filament!  Well that may not be true based on the below list.  I have been doing printing for people through 3DHubs and donating half my proceeds to the MS Society.  The other half, however, have gone to my filament inventory.  Since I did a couple of big jobs recently there may have been a splurge!  All stored in two cabinets with dehumidifiers to keep it from absorbing moisture.  I am coming close to running out of space.
