Tip 1: When restock for coins you invested, playing around the forest and the plaza, punching everything that you can-- trash bin, oil drums, and whatnot. Every one of them pops coins out when you hit them, when you relocate to a new area, they regrow, so you can gather coins for as long as you desire that way.

Tip 2: Go to the plaza and start talking to your other allies there if you presently have no missions to do. They'll send you out on missions, typically to gather a certain things, when you get enough of that things, their shop will resume. Your objective, naturally, is to resume the whole shopping center in Lakewood Plaza.
