I'm wondering if most people got a discount on the accessories they ordered with their car from the dealership? I'm in the process of deciding on the accessories I want and I'm just curious if I should expect a decent discount from my dealer.

no

I believe some dealerships are packageing these and may offer a steeper discount if you buy the top package.

I believe Rick Case Mazda in Atlanta does this, but not sure about other places.

10% here

I could get a 10-20% discount from my dealer - but many times the dealer doesn't have it stock. Often dealers that have an online store offer a deeper discount and are normally very reliable.
