I think it has more to do with the PP overload. It's saturated the last number of pages, the thread is heating up, well the book's been hot for quite a while, do we need a play-by-play on every dollar increase/decrease? There's been a major lack of new additions to this thread...
Weren't you one of the ones that said PP was going to take a nosedive?
So yes 9.6 graded copies reaching new highs of over 400 dollars is relevant.
Feel free to bring up any new books that are heating up, everyone would appreciate it, I'm sure.
For those looking for Injustice, they can be found at Barnes and Noble. I believe the first issue would have been taken off the rack in the past week or so, as the book is over a month old at this point and they only have limited space for comics. Not sure if their unsold books sit in a back room for awhile or if they get shipped off somewhere. You might also find some forgotten copies of Daredevil 21, Star Wars 1, the Batman DotF books as well.
