As a postal worker, I will agree that gamefly is ignored a bit. It's probably because we barely see any if the friggin things. Carriers put all blockbuster and netflix in it's own bin. Gamefly is put in with the flats. I mean a carrier even reads on it that it runs on the AFSM 100.
If gamefly had more mail volume I'm sure it would get the same treatment. I think their service and turn around time is inferior. I think they want someone to blame.
