The Dealer does not manufacture floor mats. So the price is all going to depend on which floor mat manufacturer they are using. As with most after market parts from a dealership, you will most likely pay more than you need to.
We are a Floor Mat Vendor for Intro Tech, which in my opinion is one of the best floor mats available. Here is a link to their all weather mat on our site:

These are a higher end, custom made floor mat that will be a guaranteed fit. Hope this helps.
