Would you mind repeating it, please?[/quote]
I said it's impossible to get a ton of money. In fact, I'm surprised you got as much as you did in only 10 hours. You can rob stores, but again, to get any real amount, you'll just have to keep playing though missions. One trick I found is that when you unlock the titan armored car, just drive it out of your garage, get out, shoot it until it blows up. When it blows us, a shit ton of cash falls out of the back. Drive around the block, come back to your garage, take the car out again, blow it up again, rinse and repeat. But yeah, unless there's a cheat code that i'm unaware of, saving money in SR is hard as hell, and even harder in the online mode.
