Gearbox Software President and CEO, Randy Pitchford, recently tweeted that fans looking for shift codes (which grant access to the golden chest in sanctuary) should keep an eye on his posts, as he will be giving out multiple-use shift codes in the next few days. The codes are multiple use in the sense that one code will be valid for thousands of people, so players will only have to stay reasonably vigilant.

Good stuff, I actually didn't get a chance to have a shift code or any of the DLC options when reviewing the game, so I'll be scouting that code like a hawk. Nice of Gearbox to give some codes away, it could only stand to increase fan loyalty. Keep an eye out on twitter, folks.
