ADV would still be going today if it weren't for their reckless business practices. It was that which sent them under, not the fans. And like I said, their singles were only better when compared to their own boxed sets of the same series' which were badly packaged and overpriced. If anything I expect the lack of people willing to pay £50 for a Scanavo boxed set was a bigger contributor to their downfall than the lack of people buying singles.
Fair's fair is a pretty simple concept too. If I pay more to collect singles, I should be getting something more than people who pay less for the boxed set. I certainly shouldn't be getting less than them! The Death Note collector's editions were only available from Zavvi and cost double the price they did elsewhere. That isn't what I call giving single collectors a good deal. If I'd bought them I'd have spent more than £100 collecting Death Note, rather than the £57 I paid to get less than the people who can now spend £42 to get the box. I imagine giving me a box and a book as extras would have cost Manga substantially less than the extra £15 I paid them over the boxed set price.
So - As a result I will buy no more singles. I'd already stopped buying MVM's. If other people feel the same (as I imagine they do) we'll see how long the argument in favour of barebones single releases holds up.
