Unless I am mistaken you only get...um...lets just say Gold, it's a yellow coin with a G on it..in multiplayer, and they have said that what you can buy in the shops is determined by your level, which is again tied to multiplayer. You get a different currency in single player that buys single-player only upgrades. That is why I am going to go to the stores, figure out how much money I need to buy the first few things I want, go to multi and get that money, buy those things, and then...something. So I can't answer the poll very well.
