Zynga is running an interesting promotion in FarmVille: every cash purchase you make in the game for the next couple of days will automatically give you one free gift from the developers.

The gift you can win by purchasing ANY amount of Farm Cash is the Alpine Goat. However, the deal only stands for those who decide to purchase Farm Cash using their Facebook Credits, but the good thing is that you can buy the Facebook Credits first (if you don’t have any left) and then trade them in for the smallest amount (4 Farm Cash) which costs 10 Facebook Credits. This, of course, will give you the Alpine Goat too, even though the actual cash bought in the game won’t help you too much…

Are you willing to give this a try for the Alpine Goat or let this special offer pass?
