    customers with a coupon are unlikely to be a representative sample

    I think A,B & C for the following reasons: A. People how often come to the store and may be biased because they know what's in the store and are likely to go there because they have a preference for products in the store B. A customer list may be somewhat biased for the same reason as A. Also, not everyone who answers the phone may be the person who purchases for the home and may be biased towards what is actually purchased C. A coupon biases preferences based on value versus true preference D. Unbiased
