Oh totally drew a blank on what you wrote.
I thought you wanted local dealers, like vendors, who give parts discounts. Local dealerships, most really do not. I would give some prices off:
Fusz Nissan:
LOU FUSZ MOTOR COMPANY
Courtesy Parts:
Nissan Parts, NISMO and Nissan Accessories - Courtesyparts.com
Then call a few dealerships and see what they can price match on. Most usually can get close but will not 100% match, try Baker Nissan, Tom Peacock, Clear Lake.
