I researched the crap out of this. Right now, your best bet is Urban Jungle. If you hurry, you can get your stuff with NO shipping costs. And I have found that shipping can make all the diffence in the world in your choice of where to buy. Here's the link.

Good luck!
Incidently, if you're looking for the Xterra seat covers, Nissanparts.com is the cheapest ($241.65 including 2nd day air shipping)
