It would be so nice if they offered the original Japanese audio as well, but still! I'm hyped to be able to re-watch the Kanto Arc in full! Although I wonder if they'll charge per episode, or a flat price for a season bundle. My experience with those retailers have not been the best when it comes to digital content.
$1,99 per episode on Google Play and $2.99 per episode on iTunes and Amazon. It says $19.99 for the season, but that may be just for the episodes listed on one page rather than every single episode of the season.
