"We've ordered parts from courtesyparts.com twice in the last couple of months and have had a good experience. Their part selection website is different than the main Nissan website and the Courtesy version seems more informative to me, but you have to cross-check the part numbers. They answered a question submitted on their website promptly. For the parts we ordered, I think they had to get them from the main Nissan location. That is OK, but it does add a two or three days to the processing time. We were pleased to get genuine Nissan parts. We use resellerratings.com a lot and did not see a rating for courtesyparts.com, so we thought we would write a review to let others know that they are OK."
