Some great advice has been given to you!
I would just like to add a few sources to Cat’s list.
I smoke a lot of what would be considered “boutique” cigars.
New Havana Cigars
Charmed Leaf
Jack Schwartz
Serious Cigars
Egars
Silo cigars
Tower cigars
I buy 95% of my cigars from this list along with Atlantic cigars that Bill has already mentioned.
