They like to get into aftermarket products in more ways than those. They work with people who like to tweak things.

If you are into looking for the holy grail of oil products, they are just like anybody else who can peddle those goodies.
That also can help you when you are on the fence and have some spare change in the wallet. I call them, teasing items.

They play on list prices on most things they sell and then have sales to make some of us feel better. If I am in the area, I get things that are completive priced, I save the sales tax and the shipping cost.

I give them their due, as if they were a bar down the street. Same products with a promised buzz but only you will know, if it did, you or the car any good.
