Brand Loyalty

The toothpaste that I use is Crest. I cannot tell if Crest is best; But it’s the brand I’ve always used. A change would get my teeth confused. For laundry, what I buy is All; A prior brand I can’t recall. My clothes get clean; I like the smell. A switch would not serve quite as well. My ketchup’s Heinz, my dressing’s Ken’s. Purdue’s the brand I like for hens. My soap is Yardley; Listerine Is what insures my breath is clean. What advertisers understand Is how much power they command; But customers they love to see Are loyal sticklers, just like me!
