I now buy most of my cigars from Famous. I've never had a problem with these folks (except for the Mi Barrios), and the cigars are as advertised. For many years, I used to buy most of my cigars from CI/Cbid, until, (a) I was burned with "not exactly as advertised" cigars, and (b) they banned me from their forum for telling the truth about what they where doing. If it's a current production cigar, still shown on the manufacturer's web site, you're probably getting the real deal. With that said, CI has a nasty habit of buying the rights to discontinued labels, slapping them on dog rockets, and passing them off as the original. If you see a discontinued, highly rated, once expensive cigar going there for cheap, you can pretty much assume that it's now a CI owned label, produced to CI's specs. In my personal opinion, these include the entire La Perla (Black Pearl) line, many of their Gurkhas, and the Torano Noventa, to name a few. Just a word of caution.
I know that many here shun the place, but I used to get great deals off of Thompson's Auction site. Things like $83 boxes of Undercrowns, $6 - $7 PAM 64s, $100 boxes of BS Maddies and $2 Tat Havana IV Nobels to name a few. I even got a box of Flor de las Antillas once for $54. But sadly, the word eventually got out, and bids went way up.
