I finally found a dealership that carries these cargo liners, not to be confused with carpet.
When I made the same purchase from Sewell they informed me they do not have it in stock.
I called several local dealers and inside the US, they informed me it is only available in CANADA!
The 2015 model, works for the 2014, to those who are concerned about comparability.
So crazy me, I wanted it, luckily dealer said they can ship to me and it wasn't too expensive either.

Just wanted to let everyone know if you're interested in getting a set, feel free to PM me and I'll provide you the dealership in Canada.
Not sure how a group buy would work, but just sharing the information.

To the right hand side you'll see the Cargo Liner, details are listed below;

Cargo Liner
$134.70 *
Protection for a long-lasting cargo area. This durable, long-lasting custom designed vinyl liner features a raised lip to contain spills for simple cleanup. Textured finish minimizes load shifting and the cargo area carpeting gets extra protection for wear and tear. The easy-to-install liner is equally simple to remove for cleaning. It's the ideal place for storing wet and dirty cargo. Consider it the ultimate way to protect the vehicle interior from scratches and spills.

Thanks!

 

Heh, finally something us Canadians get that you don't :P

 

Replied to everyone's request, sorry I didn't post it here.

I didn't want to make it seem like I'm advertising for anyone, as I am just here to offer information for those who are requesting.

 

I wanted the Lexus mat but couldn't find one so settled on weather tech. Happy with my purchase and it looks exactly like the Lexus mat just no LEXUS, LOL

 

Unfortunately Canadian accessories are sometime much different than U.S. accessories. Once you receive it, shoot us over a part # and we will see if we can obtain them as well. Thanks for the info!
