Marvel’s Ultimate Comics Universe line will begin offering free digital copies with every copy sold in January.  The mechanism will be the same as it has been for Avenging Spider-Man: a code that can be redeemed in the Marvel apps will be polybagged with each copy.  Retailers are bountied for each code redeemed in the program (see “Marvel Expands Free Digital”). 
The titles involved are Ultimate Comics Spider-Man, Ultimate Comics Ultimates, and Ultimate Comics- X-Men.  Ultimate Comics Spider-Man #6, which streets January 16th, will be the first Ultimate title in the new program.
