Definitely not. It is based on the area. Dealers bid and Costco awards them the geographic area. In my case I was in the borderline of two dealers, but both were off by about $25. I was trying to get a PA dealer north of Philadelphia but some north NJ dealer got that awarded. But over 2K more. I think it was because PA is not part of the special dealer cash ZEV states are getting. In fact, the Costco price for the dealer I'm going with already went up about $600 (still honoring the price I got).
