For all you botters out there.
Store your Space Commendations prior to patch 1.2 (Up to 1000 max, 2000 after 1.2)
You can purchase level 6,7 and 8 epic materials boxes from the ship commendation droid. Level 8 is 200 comms a box.
The level 8 from what I've read on forums is epic crafting drops from the new Operation. Even if your not a crafter you can sell all raid crafting drops now due to them being BOE.
Of note - Space missions in 1.2 ONLY give commendations for the dailys, not rerunning them.
