Just an FYI: If you have some change laying around in your account, buy all the fireworks you can carry. You get 5ea for 1 cent that you can turn around and sell for 200-300 a piece in game. Just set up shop in an area that has high level traffic (or one that has wedding appeal) and you'll bring in lots of cash in your down time.
I did this last week and made about 100k in a day... I wish I had more money in my account, but I spent most of the ten dollars I put in on expansion stones and a couple of those magic things that... what ever they're called.
So... I thought there were Ventrillo directions around here somewhere....
