Amazon has a couple warehouse deals on these that I thought I'd share.
Amazon.com: Buying Choices: ToughPRO Tesla Model X Floor Mats Set - 7 Seater - All Weather - Heavy Duty - Black Rubber -(2017) (Built From 10/18/16 To 8/22/17)
Saw a few posts around here that they did the job. I ordered some for myself. There's two more used deals available for under $50.
