"Viz Media have announced that from now through January 15th, all of the manga titles purchasable at Viz Manga (or on the VIZ Manga app) are 20% off. This includes such titles as Naruto and One Piece, Hana Kimi, Magi, Honey and Clover, Ouran High School Host Club, Boys Over Flowers, Nana, Ruroni Kenshin, and Toriko.
For those who are a few volumes behind, or in other cases, well-stocked except for a few missing teeth on your shelf, this is a nice sale to get all caught up. The store boasts over 2,000 volumes of manga in total, and there's sure to be something for everyone. If nothing else, maybe this is a great opportunity to get that one friend or family member to try starting a new series."
