While I can't say that any of the comic packs have been particularly "hot sellers" around here lately, these recent Marvel packs are really sitting around here. I haven't had any particular trouble finding the other ones either, but I think the same peg or so of these Marvel packs have been at Target, WM, and TRU for quite some time now. Personally, I don't mind them as much as some people do (although non neon colored packs would be better), but it doesn't seem like they are particularly good sellers regardless.
