Please include Call of Duty DLC in Sales

I own Black Ops 4 through and have wanted to purchase the Black Ops Pass for months now in order to get the additional Zombies maps, but it consistently remains $50. Meanwhile, the digital deluxe edition WITH THE DLC I WANT costs $40 during sales events. That’s right, I would be better off buying an entire new copy of the game than simply paying for the DLC separately. How does that make any sense? Please consider correcting this oversight and begin including Call of Duty content passes in sales and discounts.
