I like to defend Tesla, but don't count on having an easy time with returns. I don't suggest purchasing anything from them that you intend to return. Floor mats look expensive from Tesla.
I got these floor mats for free from Model3Part, from their giveaway.

Personally, I don't by anything except from Amazon Prime after reading reviews.
I think its quite important to advise people not to buy anything from Tesla that they could purchase elsewhere. I just finished a chargeback last November for some winter tires, and they email me "your tires are in the service center, come pick them up".
