Audi Affinity - Stackable?

Can the Audi Affinity discount of 6% off be added to dealer discount?
The fine print says it stacks with other regional and manufacture incentives but does not say if MSRP discount is capped at the 6%.
Essentially is it similar to Volvo A plan where dealer gets charged back if they discount past the 6%?

I guess this is not stackable, my understanding is the 6% drop not from manufacturer but honored by dealership. But I do found some dealer said they have fleet incentives, seem there is another incentives?

Affinity program is only 6% off MSRP . That’s it nothing else and no it’s not stackable with any other discounts excerpt loyalty and lease cash
