Harper is a salesperson for BrandPros, Inc. BrandPros does not sell products with its own brand name. Instead, its products are created for different retail stores and carry the store brand. Harper thought that several changes needed to be made to a particular product, but BrandPros management reminded him that the stores, not BrandPros, owned the brand.

However, because BrandPros had been concerned about declining sales, management listened to Harper$$s concerns about the company's pricing. He suggested using a different pricing strategy. More specifically, he felt that the company should incorporate a multiple$-$unit pricing strategy because it would then allow BrandPros to set a single price for multiple units. This had the potential of increasing sales and therefore profits, so management agreed to consider Harper's suggestion.
