Things To Buy With Spacebux

[Technature]

If a tier is not met should the money be refunded?

Nanotrasen should keep the money for your "Generous Donations".

To be fair it is an upgrade to something you see for the last 5 minutes of the round, so it wouldn't be that bad if the money simply disappeared.  If you're willing to throw spacebux at that, you probably don't care if you don't get it back.
