My CE got shipped from Amazon to my office (I was assuming that there would be a grace period and it would be no problem to move from early access to release) but I also took the week off. Learning that I needed the code in the box to get my CE items, I immediately telephoned my employment to call me when UPS delivered.
My excellent employer opened the box and sent me text pictures of the codes inside. He's not familiar with such things, and send me three pictures. The strange thing is that there were three codes, one for a discount, one for registration, and another... for registration. I used one and it worked seamlessly. I'll be back in the office tomorrow, so I'll see it with my own eyes... but I can't help but wonder if I got an extra registration code by accident
