Auto Parts Markup?

Yes, they did call with the price and I approved it. But the price provided was for the overall work, not a breakdown between labor and parts. Is this something that should be asked?

I understand that there is no recourse, I am just trying to understand the comment about the warranty. On the NAPA site, it states as long as the parts are installed by a Napa Auto Care Center, then the 12 month warranty applies. It does not state that I have to pay a different price.
