I fixed the spelling of the name of the store below.
A few interesting places around FC. The Shoppers Warehouse or whatever it is up the street at Seven Corners shopping center has some interesting Latin items, but its selection seems to be falling out. Looked like there were some potentially interesting Indian type stores out your way, say in Herndon, Fairfax, etc., that I have never gotten out to. If I can be of help to you in finding something in particular, let me know.
Thanks again for the recommendation. We are very fortunate to have so much international variety in this area! Likewise, please do let me know if there's anything I could help find for you.
