I love my dad, but he's not the kind of guy to sit down and teach someone how to do anything. Like change a tire or mow the lawn or whatever. I think because he's done stuff for 60 years he thinks its some innate knowledge everyone has. So I'm super glad for all the dad videos on YouTube of how to change a car battery or a faucet.
technically no one but it's built into the cost of the battery. if i go to pep boys the battery is $279 with "free installation". But costco who just sells batteries and doesn't do installation is selling the exact same battery for $150.
