Huntsman School & Office Supply offers a large selection of stationary and other writing and paper products. If you need some kind of pen or poster board or whatever, they'll have what you need (and, you'll be supporting your local community instead of one of the 'marts!).
They also have a large bookstore section, which apepars to be pretty much all LDS books. I think they are a Deseret Book affiliate or something. So, they do carry a limited number of non-LDS books as well as general Christian books as well.
I wish they carried more non-LDS books, particularly books for children. it seems to me that they would go over well, and would be doing the area a service. Just my opinion...
