Been lurking on the forums for awhile, trying to figure out what to add on to a new 2012 sport. This thread convinced me to pick up the Weathertechs, but I just couldn't see myself getting the soft liner.
So for what it's worth, I picked up the Weathertechs set: 1st, 2nd and 3rd row. Really nice fit and are a good replacement for the Costco mats I had. For those interested, you can get the entire set discounted at etruckstore.net for a little over $200 right now. I had never purchased from them, but thought I'd take a chance... saved about $57. They're doing a promotion of free shipping and an additional 10% off their price (discount code FALL2012, exp 9/30). Took a little over a week to get processed and delivered, but everything checked out and the products are legit.
Instead of the soft liner, I placed an order for the Canvasback through Wooska... 10% off code running on their site (you'll see it in the banner, code: wooska). That they claim is going to be shipped directly through Canvasback, which will ship on 9/26 at the latest. Their communication hasn't been the best, but still have fingers crossed it'll work out. I'll let you guys know how that pans out.
And finally, though not discussed here, I did get the OEM cargo cover through my local dealership for 20% off by asking if they could match mazdaparts.org. Mazdaparts was charging $188, dealership let if go $189, tax included.
All in all, damned pricey but it's worth it, right?
