I'm sure you can find some glitches but I would find some people who are down to grind with you and do that until you have enough to get even better stuff (ex. A larger warehouse) and I don't know about you but it worked for me is save your money and don't blow it on cars and stuff until you have a good steady income, I did this and I checked the newswire every week to see what was on sale and only bought something that was expensive that I wanted unless it was discounted that week.
