My old man told me when I was a lad... the part that you need for your Chev/Pontiac/Buick is in the same bin at the dealership. If you have a Chev, it costs $1. If you have a Pontiac, it costs $2. If you have a Buick, it costs $5.

He further explained that the air intake on a Chev carb was canted to the left but canted to the right on a Pontiac. He took both apart on such vehicles and showed me all the parts were interchanable and so was the price of the parts.

He took me to the intersection of Lutz and Main Streets in Moncton, New Brunswick and took me into each of four women's clothing stores that were on the four corners. He explaind that new clothing was first brought into the "expensive store", then circulated to the others in turn... all four stores being owned by the same man.

He never told me it was "marketing" a product to stunned people. He just told me that if I met a woman that only shopped at the expensive store she would want me to buy a Buick.
