In the second part of the series, in the second part of the series, we look at supermarkets and restaurants.

Dynamic pricing it could help cut down on food waste, but would it favour people who can choose when they shop? And we ask why restaurant-goers have yet to develop a taste for it.

We also find out how artists like Bruce Springsteen and Taylor Swift have experimented with dynamic pricing to set the prices for their concerts.

Finally, we ask if dynamic pricing needs to be regulated more strictly. Is it fair? Does it allow companies to get away with price-gouging? We speak to the head of a consumer rights group who says that more transparency is needed to protect shoppers.
