The Martian tie in giveaway with

We printed special editions of The Martian by Andy Weir for to include in one of their ZBoxes. The ZBox is a gift box that goes out monthly to customers who either sign up for a 3 month, 6 month or 12 month subscription plan.

The special edition of The Martian was prominently flagged in the advertising material for the zBox and served as an incentive to get customers to commit and sign up to the plan.
