What do you all spend your money on?

Quick question to all fellow raiders. Do you spend your money in game? I have been playing since launch and I don't think I have spent a single penny with the traders. It has got to the point where I am a Speranza millionaire many times over. It seems the money in this game (apart from the expedition requirement) is pointless.

Do you buy things from the traders? If so, what? Am I just being cheap because the traders seem like they rip you off?
