See's Famous Old Time Candies: A Sweet Story

This is a corporate history of a candy company, written warmly, with photographs of shopfronts and women in white aprons. It is not trying to teach you anything, which is why it is useful.

What you are actually looking at is the clearest example there is of pricing power in a physical product. See's raises its prices a little every year, the customers do not leave, and the reason they do not leave is that nobody buying a box of chocolates for somebody else wants to be the person who brought the cheap ones. The gift is the product, and the price is part of the gift.

I think about that constantly with the resort, because an all-inclusive trip for a family is also a gift somebody is buying for other people, and the same rule holds. The person paying is not optimising for cost. They are optimising for not being the one who cheaped out on the holiday.
