The Apple Pie crop makes 115 goods and grows instantly. No waiting whatsoever -- your crop is ready to be harvested as quickly as you plant it. However, 4 City Cash doesn't come cheap. I'm not too sure that I will ever be in the need of extra goods so bad that I cannot wait for a train delivery. You never know though, there could be someone who wants immediate gratification.
The Apple Pie crop is only available for the next 4 days, so it will be disappearing pretty soon after the 4th of July weekend.
Would you pay real money for a crop in CityVille, or do you think it's ridiculous? Do tell!
