Step-by-step explanation:
The circumstances in which consumers may change their purchase criteria and intentions are known as purchase decision disruptions. These disruptions can occur when consumers are unable to find the product they want, when they are in a hurry, or when the store they visit does not carry the specific brand or product category they desire.
An example of a purchase decision disruption is when a consumer plans to buy a particular brand of headphones from a store but discovers that the store does not carry that brand. As a result, the consumer may decide to change their purchase criteria and intend to buy a different brand or model of headphones.
Purchase decision disruptions can significantly influence consumer behavior and the final purchase decision. Retailers and online retailers need to ensure they provide a wide range of products and brands to meet the diverse needs and preferences of consumers.
