You must first purchase Farm Cash by one of the following ways:
 * 1) You can purchase Zynga or Facebook gift cards at your local retailer and redeem them in-game using the "Redeem" tab just above the game
 * 2) You can click on the tab that says "Farm Cash" and purchase farm cash with a credit / debit card.

After you have farm cash in your account you can then purchase items in-game.
