I've already beat the game my first time and spent the cash on skins. Then I replayed the story again and still haven't recieved any cash. How do you get more money so you can buy more bonuses?
If you go to bonuses, in game or on the menu, you see that certain bonuses have trophies next to them while others have other icons, I just quit the game so I can't check, but there are other icons next to certain objectives. Today, while playing my second playthrough, I got a 100 dollars twice, I think one them was for getting a certain amount of Fireflies dogtags. So in general, just check the bonuses and see what's there.
