As has been pointed out here already, for me it’s not so much brand loyalty, but it’s that I find what works and stick with it. Examples:
Ernie Ball guitar strings
Sharpie pens
Dunkin Donuts coffee
If at any time I discover something that works better, especially if it costs less, I’ll make a change.
Having said that, all the while certain brand names do carry an image and do have a draw. Peterson Pipes is an example for me. When I started smoking pipes this name quickly made itself known to me, and with it came a certain mystique. And soon enough I wanted one. And when I finally got one it did not disappoint.
But the question is: Was the Peterson really that great, or had I just built it up in my mind, or was it both?
