In equilibrium economic theory it can't happen because a market clearing price is aways reached so supply=demand. In the real world, markets take time to adjust, so stores offer goods at above market clearing prices for a time, and when they discover they have a surplus they have a "sale". If a toy becomes "hot" at Christmas, it will sell at above retail price on eBay because there is a "shortage" at the retail price. The same is true for tickets to popular events. Natural and political events disrupt supply chains, so a shortage will develop in local regions, for example water and ice after hurricanes.

When higher prices cannot lead to expansion of supply. For example, the demand for seats for the World CUp soccer final between Brazil and Argentina. All across the world, people would like to buy a seat in the stadium at exorbitantly high prices but supply cannot be augmented. The official price will be always lower than the black market prices.
