How do you buy equipment in the beta?

I haven't played in quite a few months so maybe I'm just being stupid, but I can't work out how to buy things in the beta (weapons, planes etc). Can someone point out the stupid mistake I'm making? :-)

Ah - I hadn't noticed that the basic weapons were all unlimited. So has the need to buy things been removed?

Yup. The only thing you can "buy" is the Condor interceptor.

Yeah, pretty much everything is manufactured or unlimited. There are threads about having to buy ammo and basic weapons when you're trying to save the planet around the forums. Even the aliens fear the auditors.

I'm sure xenonauts is going to receive a massive bill for all those gun and grenade IOUs i'm certain the supplier of flares will be a wealthy man after this is over. =]
