I noticed long ago the B&N was a left leaning store.Try to buy and order from smaller private stores while there are still a few left.
Good suggestion but I don't know any locally owned book stores . We go to Murder By The Book but they only sell murder mysteries. I'll have to research that in the Houston area.
Here in "blue country" the small bookstores are generally "mom and mom" operations if you get my drift and they NEVER carry anything conservative.
