Indicate the type of sales promotion that a producer might use in each of the following situations and briefly explain your reasons:
(1) A firm has developed an improved razor blade, but customers are not motivated to buy it.
(2) A competitor is about to do a test market for a new brand and wants to track sales in test market areas to fine-tune its marketing mix.
(3) A big grocery chain will not stock a firm's new popcorn-based snack product because it does not think there will be much consumer demand.
