How much would a complete series like Cowboy Bebop/Trigun/Samurai Champloo cost?
Bebop is one of Bandai's cash cows, it's still full price after being out on DVD for almost eight years now.
Trigun is part of Geneon's budget line now, so it can't be too much.
Join the Columbia House DVD club and get all of Samurai Champloo for like $12. That's what I did last year.
