I personally think it is one quantitative indication of value. For a same widget at a unique retail price, multiple customer can find different value. It will depend on many parameters, sometime mesurable, but not always. An exemple : a new camera has the same retail price for an influencer as for an hobbyist. The hobbyist might find a lot of value, but will mesure it by the number of picture taken or the time spent with the camera, which it will find enjoyable. The influencer may find no measurable value by upgrading its equipment, but consumers will enjoy more its pictures and therefore it will help to build a more powerful brand. Price is only one metric.
