Audi USA Promotions questions

Hello,

I see that Audi USA FS is doing a “Winter” deal. They offer a " $4,000 National Customer Credit Bonus*

Receive a $4,000 customer bonus when you purchase or lease a select, new 2023 Audi Q7 45."

But, also they say that they offer a " PROMOTION

$1,500 National Customer Credit Bonus*

Receive a $1,500 customer bonus when you purchase or lease a select, new 2024 Audi Q7 45 or 55.*

Offer only valid 11/01/2023
through 11/30/2023"

Are those two promotions stackable? Is that also stackable with Costco?

Thanks!

Can’t stack a 2023 with a 2024 promotion. Pick the model year you want.

Costco is stackable with the 2023, not sure on the 2024. If you don’t have the cert yet, you are too late as it must’ve been printed by 10/31
