I don't know why everyone is assuming low numbers = high costs. Highly niche market movies like Bubba Hotep came out in the 14 dollar range. so too do the myriad direct to DVD movies. Are you guys telling me that python versus anaconda sells more units than shows like Transformers? Or that Disney/Pixar movies which always sell for 20.00 retail are a niche market comparable to anime shows like eureka 7? Manufacturing costs on DVDs is very low and it doesn't cost that much nowadays to master a disc either.
I think most people want to do the right thing. They want to buy and not steal, they just don't think the inherent value of a lot of media is worth the asking price. and since it's so easy and annonymous to steal, they do it. Personally, and I think many people would agree, anime shows charge top dollar and seem to provide little in return. Most discs are no frills ports of the show with little or nothing in terms of extra content, yet they ask as much, if not more than 2 disc Special Edition discs that offer hours of extra material as well as commentary. I'm not condoning priacy, I'm just trying to give an insight into why many people d/l and then don't buy the discs.
