I could spend all day at Barnes& Noble, drives the wife nuts , but 10 year old daughter is same way could spend all day just looking at all the different titles.
Military book club was cool to it's hard to go thru the catalog and pick just a few books when there are so many to choose from. Recently picked up a book on military air craft 1945- 2000. $ 20.00 dollar book full of tech drawings for $ 9.00
my " refrence" book shelf is groaning under the weight of 1/2 price book store buys that are sooo much cheaper than the book stores and they carry everything.
