Conn. Gen. Stat. § 12-326c: Sales between distributors.

When one distributor sells cigarettes to another distributor which has the same presumptive cost of doing business, the former shall not be required to include the markups provided for in section 12-326a, but the latter distributor, upon resale to a distributor which has a different presumptive cost of doing business or to a dealer, shall be subject to the provisions of said section, provided, in no event, shall any distributor sell cigarettes at less than the basic cost of cigarettes.
