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!
