Great place to kill time! I can definitely get lost in book stores for hours. Books-A-Million is no exception, except they do have more than just books to offer inside as well.
There is a well stocked board game area, some movies, and other gift ideas from journals to reading lights. I think my favorite thing I saw during my last visit was that the comic section had more comics as well as action figures and toys to go along with a healthy selection.
There's a coffee place inside the store of course, but I did not partake.
I'm still an Amazon guy myself, but something about picking up a book, the weight, the smell of the paper, and the excitement of finding a good read in a book store still has be coming back.
The other strange thing about this location is the availability of the Nook... which is Barnes and Noble's e-reader. I would think you wouldn't want to carry the competitor's e-reader, but oh well.
