Greetings and welcome!
Im located at the top of the left coast and have bought from all of the venders at one time or another. Just this winter, I have spent around $12k on parts from the venders. Shipping is always expensive for me, because of where I live, period.
That said, I have streamlined my #1 go-to parts supplier based on other "value" that I can directly relate to saved money. I save money in the form of; being able to talk to someone directly that *knows* Bronco's, a company w/ high integrity standards, easy to work with, a company that has the part in stock 99.9% of the time when I make the order, I choose mainly to deal w/ my perfered supplier because 99.9 of the time they send me what I want -when I want it without excuses and this action tells me loud & clear that they apprciate my business.
My perfered parts supplier is located in a small town in the upper third of the biggest state on the west side. Regardless of where this supplier was located I would still choose them as my go-to parts suppiler because they save me so much money/time -as outlined above, that a seemingly expensive freight bills means nothing in a mutually good business relationship.
