There are a couple of places:
Centro Leon
Supermercado Nacional
Cigar store at the Gran Almirante.
However, none of these places has what you could call "great prices"
You'll have to wait until January for the factories to open again (around the 15th) if you want to get good prices..but only if you know the owners....
When I get back, perhaps we can sit, sip and contemplate your academic future with a nice cigar....I happen to have more than a few.....
Now if only you played bridge and golf, you'd be perfect!!
