Yeah for the shows I've really enjoyed that have provided be with hours of entertainment, I wanna support them as much as possible and keep a local copy of it for myself. Not to mention all the extra stuff they also sell like art work, redone scenes, animator Q&A's, etc.. But I'm a cheap bastard.
I'll probably end up buying the Bakemonogataari Blu ray later this week just for the sake of that show, but fuck I wish they made this stuff easier to access with cheaper prices.
