Putting a price on a loaf of bread, a new pair of shoes, or train ticket is something that everyone is used to doing. We expect prices to be associated with these things; we can compare one loaf of bread to another, understand the value of a pair of trainers compared to a pair of flip-flops, or take a train at a different time. Pricing of less material things, like the experience of being in or going to see a music group, can be trickier to navigate.
