Keep in mind that your local retailer may not have all of this crap, yet they may also ADD some stuff at their discretion (like overstock or other crap they have lying around).

Also a few non-comic freebies-- like a special HeroClix Iron Man and other junk. If you get the Iron Man and don't play HeroClix, sell it on eBay, pronto.

NASCAR comics? What the hell would they be about? Oh no, the tire's flat!

NASCAR comix is the best thing I have hear in a looooooooong time. Now the rednecks can't make fun of us as they stand beside us at the store buying comics.

True. Plus if you think about, when reading a comic, all you do is turn the pages to the LEFT. So it's a natural fit.
