The code promo that's going on now is one of their random deals. Not everyone will get one, but double check your spam folders just in case. Not sure if emails are still going out, but I got one four days ago, and usually they go out in waves over the course of a couple days.
But yeah, I was on px two hours after launch, was told by a PM that it took three days to hit 25k, but never got the email. I think when they had to delay the promo because of the res rune issue, it caused some problems with their list.
