I always bought a couple of packs at a time ($6.73). What started me with e-cigs (just last week--I am new here) was that I decided to
buy a carton before some bad winter weather, just in case I couldn't get out. $70. I was like wow! Bought a couple of OTC e-cigs when the carton was gone and then went looking online for them. Haven't had a cigarette since the first day on e cigs. Hoping stays that way.
