Are you looking for a site for legal cigars (NOT cubans), in bulk? Your post is less than perfectly clear.
There are many companies that people here use to buy cigars from, the largest are likely Holts, JR, and Cigars International. There are many, many others that often have great deals. Above that, many smaller shops have gone out of their way to make great cigars available on line. JimD (Hartford, CT tobacco shop), puffstuff (can't remember the name fo teh shop...sorry!), and MD Cigars are a few that I can think of off the top of my head. The big thing is to do some research, and check prices at a few places, don't jump on a deal becasue THEY say it is a great buy! Then, check around ehre asking about that vendor, and you can get a feel from members what their experiences have been.
If, on the other hand, you are asking about illegal cigars, you should probably take a few minutes and read soe of the rules on that topic.
