What are examples of products that have elastic demand, and why do their prices fluctuate significantly in response to changes in consumer demand?

Examples of products with elastic demand include luxury goods, such as designer clothing and high-end electronics. These products have elastic demand because consumers can easily substitute them with cheaper alternatives if their prices increase. As a result, their prices fluctuate significantly in response to changes in consumer demand because even small shifts in demand can lead to large changes in price to maintain sales levels.
