Thank you for the info. I just wanted to confirm that Shift doesn't send you a code for the second key.
I guess I'll just have to wait and see how many keys I have when I get back to Sanctuary.
It's not a code even though it sends you to a code screen. Once you confirm your email you should get it. May have to reload a game after but even when I loaded a character I already started I got the notice of my second key.
Yesterday I had trouble confirming. Asked for another confirmation email from the website, and it had me login and create a display name. Once I did that I got it... no other emails were sent.
I'm assuming the code page is for future Shift rewards.
