When shopping for a smartphone, a consumer first compares prices to see which brand offers the lowest price. After also inspecting the product features of the various phones, however, she decides that the lowest-priced brand is not her choice. Instead, she selects the brand with the best features. This outcome is the result of the chosen brand's unique value claim that is known as: 1) economic value. 2) functional value. 3) experiential value. 4) social value.
