Name Packages (example “Family Pack”)

Add a sliding card, just below the total, better if it has a discreet but catchy effect (glow or shine or shadow or heartbeat, etc) that says something like: Your current selection is "$xx", if you add "x" more boosters/antennas/ W/E, you will be saving "$xx". Then a button "Yes, add "x" more boosters to my order"

Instead of the sliding card (or split test vs sliding card) change the content of the FOMO to notoriously reflect some cases where customers bought more than one. Easier and faster to implement than the sliding card, but the lower possible impact in performance.

Add discounts or "net save amount" to each booster quantity row. We want them to know how much they're saving with each package.
