I used to love ordering the catalog from this one company that sold all kinds of great stuff for SAS/CAS, etc. They had clothing from Wahmaker, Scully, etc as well as assorted dry goods and period-correct gear (I used to do some reenactment with the Arizona Rangers).
Can't for the life of me remember the name of the company or if they're still around!
I need to so some shopping for the missus!
