A new C.A.O. promotion that began April 1 allows cigar smokers to choose the next C.A.O. blend.

Retail cigar shops are now selling three-pack tins called Last Stick Standing that are free with the purchase of any six C.A.O. cigars. There are three cigars in each tin, each measuring 5 1/2 by 54, named C, A and O.

Each is made with a different blend. Cigar lovers are encouraged to light them up and decide on their favorites. Rating a cigar gives you the chance to win a box of the final blend before it goes on sale to the general public. One winner will receive a trip for two to the C.A.O. factory in Nicaragua.
