There are limited weekend dates for this one at this price so if this works for you do not wait (you have 24hrs to cancel free btw).
It looks like MAY is wide open for weekday ones too for the PHX one. If you would rather not red eye you can consider changing to LAX as your end point and at a slightly higher CPM (5.5) to do it out and back in a day on server weekends in April/May.
Here is the lowest I found:
4,386 MQMs at 4.5CPM
Bookable on Delta.com
PS – If you have FlexPerks points, look at booking two days back-2-back and you can spend just 20,000 points for two tickets 😉 #Tip #Winning
