From the app...go to "the books" section on the bottom...you will see the two movies there. As long as you are doing it from the tab s, you will get a code once you click on each movie. I believe it is limited to 200,000 codes per movie so it is until supplies last.
Not to totally derail this thread, and my memory may be faulty, but I thought there was some kind of continuing offer for freebies on a monthly basis that came with buying the Tab S??? Or as noted, are the gray cells burning out????
