Which of the following is most likely used by a seller to target an impulse buyer?

a. contest

b. coupon

c. display

d. rebate

A coupon would work best of all. If you had a contest, the buyer might still go to the competition store. A display is just cool-looking and won't do much. A rebate isn't always guaranteed and isn't immediately saving money. The coupon would give a sale to the buyer.
