For some reason, my comic shop thinks I "requested" both covers of Infinite Crisis every month. And, every month, I have to go through my subscription stack and remove one of the issues with a "You put two in here..." comment.
But, when it comes to my comic shop, it could be worse. Ask thedoctor about that Superman-Red Son DC Direct he ordered back in 1982....or Cross whether he gets Fantastic Four or Ultimate Fantastic Four...
