For one week collect all the coupons you find in newspapers, magazines, mail, and so on. What percentage are for products or services or brands that you would really buy? Typically, how many coupons do you actually use in a week? Pull all the coupons for one product category and visit a store.

Are there other brands of that same product that do not have coupons? Is the store engaging in any other methods to attract customers—rebates, sales, contests, multipacks, and so on?
