In addition to the new FDA regs there's another reason to start buying in bulk soon. On the ballot here in California is Proposition 56 which is expected to pass by a wide margin. This is from the official voter's guide:

" A YES vote on this measure means: State excise tax on cigarettes would increase by $2 per pack—from 87 cents to $2.87. State excise tax on other tobacco products would increase by a similar amount. State excise tax also would be applied to electronic cigarettes."

Everything is about to get a lot more expensive.
