There are many Sites that let you buy Cigars at the Age of 19 and some of age of 18. If your local state don't let you buy cigars unless your over the age 21, Then don't try and buy online as they do try and follow your local laws as well. Thompson, and Jr does for 18 unless your in the state of Al, Ak, NJ and UT then you must be 19.

Good luck
