This is certainly not going to be much help so apologies in advance. I bought my copy of the book immediately from North Star as it was obviously going to sell out and fast. I've pre-ordered Lion Rampant: A Viking In The Sun too as I expect that book to sell like hot cakes as well.
What I'm saying really is obvious, if you suspect you are going to use any of the Lion Rampant supplements produced by Edinburgh Uni buy them fast as they go very quickly.
Hopefully they will get a re run through the press though I don't know how that would work as Osprey are not the publisher but the Edinburgh University who are obviously going to be more interested in publishing academic tomes- and rightly so.
EDIT: Thanks to a health problem and Covid together which has prevented me from getting to the club, I haven't managed to give the LR Crusades book an outing even though it is very popular at the club.
