To be fair it is difficult to justify, especially as many comics read better in the trade format anyway and in the most extreme case of someone like Warren Ellis he doesn’t seem to give a shit about writing for monthly comics, it’s a means to an end for his trade collection. On ‘Trees’ he ended issues mid conversation that pick up on the first page of the next issue.
I’d love to see the real numbers we are all denied on comics because our debates are all based on issue sales and yet nobody much here is buying them and those that do give ‘pull lists’ of 2 comics. I pick up about 3 DC comics a month but the rest I either buy in collections or when other publisher like Image sell them half price after one month, again making them more money than if I bought the floppy at full price in a comic shop.
It’s not really about being able to afford them, it’s just why pay so much more when there’s essentially no benefit other than being first and if anything major happens in a comic they tell the Hollywood Reporter on the Monday before it comes out anyway.
