Surge pricing

Dynamic pricing, according to surge pricing, is a pricing strategy in which businesses set flexible prices for products or service based on current market demands. Businesses are able to charge prices based on algorithms that encounter supply and demand, and other external factors in the market. Dynamic pricing is a common practice in several industries such as hospitality, travel, entertainment, retail, electricity, and public transport. Each industry takes a slightly different approach to re-pricing based on their needs and the demand for the product.
