Animal Crossing: City Folk Tips

Fastest bells ever
My sister and I both have this game. Both Wiis are on different dates. My town was on a Sunday AM and Joan was selling her turnips for 100 bells. My sister's Wii was on a different day of the week where Nook was buying them for 500 bells each. I left my gate open and while I would buy 1500 turnips and drop them off at the gate she would come back and forth between towns to sell them in her town. Turnips don't go bad when the Wii's are on different dates and just crossing towns. We made 5,000,000 each once we split the profit in two hours strait from an initial 200,000 bell investment.
