Dont do it ! Have Ferre send you some smoking supplies
I too try not to run out, I hit the reservation when I'm down to one carton left. Then go buy about 5 - 6 cartons to hold me over for oh about 2 months.
Also when I get my fresh supply I usually try and put a pack in the car glove compartment, another in a coat pocket in the closet that I don't wear much, and one somewhere in a drawer, for just those emergency situations.
Awful habit, but I can't stop, and I feel your pain, I will go right now and have one for you
