I'm glad I commented, then. For the previous weeks, the $360 offer was showing. On April 3rd and 5th when I checked, it wasn't showing for me. Today, I checked again, and now the deal for $360 on medium is back. I guess I should pull the trigger before it disappears again.
And yes, I was signed in each time and Pixel 2 XL in all cases.
Edit: dang. I guess the system was wonky for me because I am on $40 5GB plan and won't let me keep it.
Edit2: ordered on small tab.
