If your situation is seriously rural, it might be a few days between trips into town (or to your P.O. box), so while you could get different media at Redbox on every trip, you would have to plan to overlap returns and requests on Netflix (perhaps with multiple accounts?) to get new content on every trip. I am extrapolating from seeing a number of battered rancher pickup trucks whose occupants are clustered around Redbox kiosks in small towns in the western US.
