Spoke to a couple of the East Coasts larger comic shops and they seemed to be saying the same things about the 3d covers. Now these are bigger shops who were not heavily allocated like many small stores were, and were able to get in many copies if the enhanced covers. The ones that are selling out the quickest are Flash Grodd, Superman Bizarro, Batman Ventriloquist, and Desaad.
To quote one of the retailers who didn’t want their name printed so they don’t tip off their competition, “The ones that are going to be the real hot movers this week are Bizzaro and Ventriloquist. Bizarro has a ton of popularity, and is a cool cover, and Ventriloquist is for the batman completists.”
I can say I was surprised at how low the books have been selling for in eBay considering how much they were going for before their release. Only time will tell how they will end up.
