Waiting for the Trade

I've heard a lot lately about people waiting for the trade paperbacks to come out instead of picking up the monthly comics.

I guess that's what I'll have to do with Afro Samurai. I missed the first episode, and it's nowhere to be seen. So, I've deleted the multiple copies I have of episodes 2 and 3 from my DVR and will wait for the DVD to come out in May. Maybe the local Florence, AL stores will carry it.

But why does the uncut version cost twice as much as the edited version?
