SECTION 1.  Section 295E of chapter 94 of the General Laws, as appearing in the 2010 Official Edition, is hereby amended by striking out the first paragraph and inserting in place thereof the following:-

The price posted on any pump or other dispensing device from which motor fuel is sold, as required by section 295C, shall remain posted thereon and continue in effect thereat for a period of not less than twenty-four consecutive hours. No retail dealer shall sell motor fuel at any price other than the price so posted at the time of the sale, regardless of payment in lieu of cash pursuant to section 28A of chapter 140D. A retail dealer of motor fuel shall not charge a different price for motor fuel if a consumer elects to use a credit card in lieu of payment by cash, check, or similar means. No premiums, rebates, allowances, concessions, prizes or other benefits shall be given directly or indirectly by any retail dealer so as to permit any purchaser to obtain motor fuel from such retail dealer at a net price lower than the posted price applicable at the time of the sale. In no transaction in which a retail dealer may fix or set a single price or charge for the sale of a quantity of motor fuel, together with some other commodity or service, shall such single price or charge be less than the aggregate of the charge, in accordance with the posted price, for the motor fuel involved in the transaction, plus the charge for such other commodity or service when the same is sold or rendered separately, rather than in combination with the sale of motor fuel.
