I thought the same thing; I purchased some $20 mats from a well known retailer (Walmart) to get through last winter, in anticipation of the release of the digital fit Weathertech floorliners, that were not yet available. Those cheap Chinese manufactured floormats stunk (obnoxious odor) so bad that I had to remove them.
