Parts! Bend over AND smile! short rant!
i just went thru this with tune up stuff for my D300 w/ a 383.
built the cart out at rock and cross shopped amazon. rock was still cheaper and had everything i specifically wanted brand/quality wise. the only thing was they didn't have a cap & rotor set with brass lugs, it would have to ship from another warehouse-- daggers-- but i still had the pricing. they didn't have autolite's either.
so i went to the local napa to get the plugs which wasn't too bad, only like $1.25 more than whatever rock had. but i asked them if they would price match the rest of the parts list and they either couldn't or wouldn't or didn't have the parts. even with the cap and rotor having to ship from another warehouse and getting dinged on shipping it was still less than half the cost than napa. the belts-- exactly the same brand, quality and part numbers were nearly 4x the cost.
yeah, i wanna support local but not at that cost. and not when your parts counter doesn't know a damn thing.
