It's been a while since I did this and I thought it would be good to update it. The only direct comparison I couldn't make was the timing set. Everything else has the identical part number.

A little SPIN OFF of this topic ....

China Mart or Hobo Fright vs say Snap On .....

That cable operated hose clamp plier ....

Snap On (much fancier than the CM piece but probably made there) ....150$ PLUS !!

The CM piece on eBay delivered to your door ? 15$ !! ... or less !

6pak, any idea on the shipping costs from RA on your list comparison ?
shouldn't that also be added in as well ?

Excellent point. I'd estimate about $100 for shipping these items. The reason that I didn't address shipping initially is that my local NAPA store wouldn't have any of this on the shelf. Their stocking warehouse probably wouldn't have anything other than the gaskets on the shelf. So my NAPA store would charge me freight from a district warehouse like Minneapolis or Denver. Short answer, it's a horse apiece.

Edit: This was an interesting question so I actually filled out a RA order to see what shipping was to me for the parts list I used for the comparison. $75.96. Less than what I thought.

We've got 4 local shops so close together you could pretty much throw a blanket over all of them.
That being said, of the 4 I typically go to Advance Auto, but order the parts online for in-store pickup. I apologized to the Manager once and he acknowledged the online discounts made it a no brainer. He was pushing to be able to offer the discounts for walk ins, but it was shot down.
Auto Zone is sketchy at best. I went to the local NAPA a couple weeks ago and it was a ghost town. I got tired of dealing with their superiority complex but needed an industrial belt (they were out).
I've been slowly shifting to O'Reilly's. So far they have had everything I needed at a decent price and the counter guys a) know their stuff, b) don't have attitudes and c) are more than willing to give suggestions for other options if they don't happen to have what you need.
I will admit that wiper blades always come via Rock Auto. I can replace them on all 4 vehicles for what it would cost to do one if sourced locally. And yes, they are the same parts.
