Mercedes Good Or Free Deals No problem! Charlene I have never used these before.. do i use the code to checkout at the location? thanks Mercedes Hi Charlene, before you select your movie, you need to select “check out with promo code” or omething along those lines. Then pick your movie, go to check out. you will still need to swipe a card but if you only rent one movie then it should be free. Mercedes Giselle Free movies? yes please! I love these machines! Charlene Thanks!! Going to try now!
