I'm sure this is not news to most people, but for what it's worth....
I looked up tires at the Firestone website, picked out the tire I
wanted, called the closest shop and then went in the next day. When I
got there, they "were out" of that tire. But had the next more
expensive in that type on hand for $15 more each. All the specs,
including speed rating, etc., were the same online. I asked what's the
difference, and was told "this one is a much, much better tire." So I
thought, $15 is OK -- better tire and I can stop checking around.
So the salesman wrote up the order, and the total for 2 tires was $95
more than the cost of the tires. I was surprised at the total and asked
him to break it down. That included required charges (tax & disposal
fee), installation, balancing and 2 different warranties. Removing the
warranties, the total was sill $60 more. Which was OK, but add the
extra amount for not getting the tire I originally wanted, I decided to
Long story kind of shorter..... I called another shop of the same brand,
they sold me the original tires I wanted, and got out with the total $30
less than the first shop.
Also, I asked the 2nd shop what was the difference in the 2 tires, and
he said "nothing except just one has raised black letters on one side."
I know this is not much of a price savings, but the point is - the first
shop was not being truthful but was within a mile of my house. The 2nd
shop was truthful and 5 miles away. So everyone loses, except the 2nd
