You're assuming they buy their cigarettes at CVS instead of a grocery store or convenience store. Really, who goes to CVS unless you're looking to fill a prescription or buy aspirin?
They will get the message loud an clear that CVS does not value their business, even if they do not purchase them there.
I go to CVS to buy my cigarettes. Do not get my prescriptions there or buy asprin. They have the kind I like at the best price.
I don’t care if they stop selling them, what I do care about is the phony it’s about health. If that was true they’d stop selling half the crap in their store.
