Rovio has started its Christmas sale a bit early this year as it has just slashed the prices of all iPad games to $0.99. This sale includes the entire Angry Birds series, even the newly released Angry Birds Star Wars HD. Rovio has also cut the prices of Bad Piggies and Amazing Alex to the same price-point of $0.99. This sale runs until December 17th. These games normally retail for $4.99 a piece, so if you think you’d like to play them at some point in the future, make sure to download the apps now to save a few bucks in the end.
