Who doesn't love free shipping? Well, Irrational Games presumably does, because they're offering it through the official developer store.
The free shipping offer is going to stay valid all the way to December 23, right before Christmas, which should make shopping for your gamer friends and loved ones a little easier.
As Irrational puts it, this ensures BioShack fans will be "decked out in the latest gear and that those heavy Collector's Editions make it home safely at launch."
Keep in mind that the "free" part only applies to US residents. However, international shipping has been marked down 50% during the same span of time. The offer ends 11:59 PM Eastern time, come Sunday, December 23. Of course, there is that annoying disclaimer about how all this is subject to change at any given time.
Anyway, head over to the Irrational store for a look.
