Google introduced a 'Deal of the Week' last week, offering an app and a game for just $0.20 each. The Deal has been updated and this week it's:
WeatherPro
Angry Birds Star Wars II
WeatherPro is normally $3.67 and Angry Birds Star Wars is usually $1.49.

I was a fan of WeatherPro until they added in app purchases for everything even after you purchase the app. Do yourself a favor and just use the free version of Willy Weather or buy Pocket Weather, they are both far better apps.
