When you shop for cola are you loyal to a brand like coke or Pepsi or do You shop based on cost?
If you walk down the cola aisle you may notice your favorite soda on sale. If it’s Coke do you buy Pepsi or vice versa. Regardless of the product do you purchase the product that is on sale. If so, you are a marketer’s worst nightmare. If not, then the marketer loves you and wants you to buy as much as possible.
Shop on either for sales or for brands.
