I'm still clearing my Iron Man bonus. If you look near the bottom of the page you linked it tells
All players with an active Iron Man Mid-Year Bonus are eligible for the Deal Me In Bonus. If you clear your Iron Man Mid-Year Bonus in full before 23:59 ET
on Thursday November 29th
, you will receive your Deal Me In Bonus offer by 23:59 ET
on Friday November 30th.
Players who have not cleared their bonus in full by this date will receive the Deal Me In Bonus offer by 23:59 ET on Thursday December 20th.
So you should get the bonus offer by December 20th. Just keep checking for it. I'd imagine they'd send an email about it too but maybe not.
