So i decided to login to APB in the light of a new developers and shed some of my hard earned money because i noticed the launcher screen shows a Buy one Get One joker box. See here for a visual of what i'm talking about. Bought a nice handful of Joker boxes but never seemed to receive any free ones. Anyone know how long it takes to get them and/or what i need to do to receive them? Thanks in advance
