Yeah I wondered that too. Darn fixed pricing! Then I read about the company and how they manufacture in the USA with American labor and their machinery is even made in the USA. Not to mention they make a top notch product. So I thought about it and went ahead a bought some floor liners for my daughter's gti. I would have liked to got 15 percent off but it wasn't going to happen.
Yeah the way they distribute is a little odd too. Depending what you need they may have to make them up which takes a few weeks. There are some larger stores that may have them in stock but they will charge you a premium for them.
Their vendors are allowed to sell them a bit cheaper, this combined with shipping savings makes that the best option IMO.
I got my floorliners for $155, MA tax and everything included. Saved a few bucks and supported my local tuner shop.
