For those that are interested the DC Universe 10th Anniversary 30 animated films is on sale on both iTunes and Vudu for 50 dollars (lowest price thus far).
All the movies should be moviesanywhere (MA) so once purchased you should be able to watch on the platform of your choice. That being said I recommend iTunes as iTunes has some of the movies in 4k and that will transfer the 4k digital license upon purchasing over to moviesanywhere in 4k while vudu only has it in HD only. Purchasing the bundle through vudu will result in you owning all the movies in HD only.
In addition some of the newer DC animated movies like Catwoman hunted and Justice League War Apokolips are also 4.99.
That being said, I believe all the DC animated movies are currently available on HBOmax for those have a subscription.
