I am HUGE advocate of supporting your FLGS and your local book store.
If you have the choice, please always support your local stores when you can.
That all being said there is a new online book store that I am calling "The Book Store of all of Tim's Favorite Things."
Wednesday Mourning from "Oddities: San Francisco" has started a new online book store Orphic Vellum Books.
You can read about it here: http://wednesdaymourning.com/blog/?p=18#comment-38
And see the store here: http://www.wednesdaymourning.com/zencart/
A lot of the books I would want here I already have, but I am hoping to see more soon!
The place looks great and getting these old books would really be nice.
If you buy something from her tell her I sent you!
Not that it would matter at all, but I have always wanted to say that about something...
