I have 500-1000 red box codes for free movie rentals and I was thinking about how to monetize them. My thoughts are to put them on a content locker and when they complete an offer give them 10 or so codes. The codes are reusable as long as they are used by a different CC. So my thoughts were to set up a content locking site and when they complete it, it gives them the codes along with the links to a few other sites where they can get even more codes. What do you guys think any help on this? Also I am taking any recommendations on the content locker as I have never used one before other than leadbolt and I am tired of getting scrubbed by them.
