Keep an eye out on eBay. It seems like they are always on there -- except for right now. Here are some
auctions. You could use these costs as a reference, or contact one of these sellers (as they are typically a business and have additional stock). If you are not in a major rush, create an eBay search to email daily about the floor mats.
In my Ford Explorer and Chevy Impala, I purchased these heavy rubber ones from WeatherTech. I think they are awesome.
I always scratch my head and wonder where the weather, etc. is so nice that you can live with fancy carpet ones. Granted, folks must have nice garages, and clean their vehicles better than me.
All the best to you.
