FarmVille is a great place to go to escape the rigors of everyday life. You can get back to nature and enjoy the peace and tranquility that comes from working on the land. However, not everything in FarmVille is an escape from the ordinary. You still need money for just about everything you do. You have to buy the seeds to plant, and you'll even have to pay a small sum for each plot of land you plow.
These costs are easily managed of course because you're harvesting and selling your crops for more than it cost to plant them. There are a lot of other items you can buy in the FarmVille market to decorate and build up your farm, and you won't be able to get these without some significant sums of cash. Buying these items will also get you some much needed experience points to help you advance to the next level, so you'll have to find a way to make sure you have enough money for all the discretionary items you want to buy.
