I have a suggestion that might make the store better.
On pages where roleplaying books are advertised I think the ISBN and the number of pages the book contains should be listed at the end of the product description.
Like for example, at the end of the description for the D&D 3.5 PHB, the ISBN is listed. Below that it should also list the number of pages and whether or not the book is hardcover (I know that's copying the White Wolf product catalog, but hey it works :-p )
I just find it annoying when I see 'hardcover' listed in the title of something instead of it being in the product description. I also find the spelling and format errors increasing at a staggering rate. I didn't mean that as an insult just as a suggestion.
