Personally, I have never had anything but good experiences from Famous. I am sure this will be a lengthy thread since the vast majority are intimately aware of them. Don't expect the newest stuff out quick or HTF sticks very often. But the Monster deals can be amazing (Just this week bought a 24 ct box of Oliva Serie G Maduro Belicosos for $31), as can some of their promotions. Not much on their in house exclusives and such myself, but I have certainly bought a LOT of cigars from them.
They always ship within a day or two, usually well packed, can't remember a problem. The one time I ever had a damaged stick was a damaged pigtail and they refunded it immediately and let me keep the stick. All in all, a really good online retailer, mostly from the deal/stock up category though.
