Have fun! When I was there last Summer, many shops had very limited inventory. Surprisingly, even though it was a very small Estanco with only one cabinet style humidor, check out Estanco Juderia when you're in Cordoba as it's very close the main attraction of the Mezquita. They had the most variety available of most of all the shops I visited on my trip. If you're looking for singles, this place was perfect. I was even able to get a full box of the new Spanish RE. Also, I'd recommend you walk into any Estancos you walk past as I was able to get the Spanish REs in 3 different random hole in the walls, probably because they weren't well known to cigar enthusiasts.
