That the Mobil 1 ($24) and the OEM filter at $21 would total around $45....the most I've ever paid for the components to change engine oil...even on an 8 cylinder engine.
Exhorbitant prices are a relative thing, I guess, and depends on who is talking.
I am thankful that I have the ability to perform such an easy, almost mindless task (that sometimes can get you dirty enough---like when you accidently drop the filter into the full drain pan...LOL) but I know it has been done right then....no loose drain plugs, filters or the like and I don't have to "bend over" for anyone looking to justify their high shop rates by overcharging for such a simple service task that needs to be done.
I'll leave the transmission or engine changes for the dealer....maybe....
