I paid 275 for front and back ones last year. I wouldn't recommend anything else. Not only do they look good, especially after a quick spray with a pressure washer every once in a while, but my carpets looks brand new underneath.
Check Cabela's for the Cabela's Trail Gear 2 Floor Liners they are made by WeatherTech. I ordered mine from Cabela's and they were shipped from WeatherTech. A front and rear set is $179.98, use promo code WGIFTS good through 11/29/11 for free shipping.
I looked on eBay and found a set for $199, but with a "make an offer" so I offered $175 and it was accepted. Free shipping too.
I also found Husky Liners on Amazon for $125 and was going to order, but then found my eBay deal was accepted.
also, you pay a little more for these products, but remember, designed, made and produced here in the good old usa by a us company. aside from being imho an excellent product, i consider it patriotic to buy these products. i also get to feel like i am "sticking it" to china!
