Apple is planning to offer special promotions for the holidays in the Ap Store, that might include apps and games for free.
From the 24th to the 29th of December there will be a new surprise everyday in the App Store. What is more likely is that the promotion offers applications and games free download, similar to the promotion 12 Days of Christmas Apple released some years ago.
In New Zealand, the promotions have already begun with purchases of promotional packs within the application Looney Tunes World of Mayhem and a three month subscription for the price of one in Canva.
