Hi I think if you have a Barnes and Noble or Borders Books near you they can have it for you in 2 or 3 days. I got the 2009 John Brierley guide which seems to be the most popular one. I ordered it from my bookstore and had it in 3 days.
I returned to St. Jean Pied de Port a couple days ago after completing the Camino. In a bookstore I was surprised to see a few copies of John Brierly´s 2009 guide. I hope you get a guide before leaving, but if you land in St. Jean without one, check out the local bookstores.
