Cafe World: Choose the next diet Mountain Dew flavor for 2 free Cafe Cash

It seems the Morning Glory trailer in Cafe World was just the tip of the iceberg; that survey only netted players 1 free Cafe Cash, but this new one from Mountain Dew is offering 2 free Cafe Cash. All you have to do is vote for the next Diet Dew flavor. There's eight new choices, and your job is to choose two out of the eight for a blackboard showdown.
