FUNimation Entertainment has announced on their blog that due to a packaging error on their part, Fairy Tail Collection 9 is being pushed back from its original August 15, 2017 release date to September 5, 2017. The date change is a result of the incorrect DVD and Blu-Ray discs being included in collection 9.
Customers who have pre-ordered the set will receive these incorrect discs. The company is working on a solution to make sure these customers receive the correct discs as soon as possible, and says they will be updating their social media with more updates as they become available.
