Huh, in hindsight I suppose I should've clarified that. But by exit out I mean the game. Had bought the plate armor but had to go, so I closed the game. When I came back, I noticed I still had the armor. But my money was back to what it was. Out of curiosity I tried other stuff and it worked. Kept all armor, weapons, and upgrades. But money goes back to what it was before buying.
