Little things like toothpaste and razors are simple to modify. Just changed brands, then continued to buy the new product out of habit.
While I don't check everything I buy, the things I do alter satisfy my monkey-brain's impulsive insistence to respond to these companies, so I don't think on it again.
It was easier to switch away from Costco and Target than I expected. The competition is literally across the street. While the competition still have their issues, they don't stick in the mind currently.
