Just want to toss this out there for people who may not have a GS close to them and is having trouble getting a code:
Give them a call. Every GS has the capability to print as many codes as they need through the computer system, they just print on a receipt like a pre-order bonus code. I ran by yesterday to pick a code up and they were all gone, but the guy told me about the "on demand" style system they had. They can print an infinite number of codes, so you might get someone who's willing to read one back to you over the phone.
