Answer:
This is an example of limited problem solving.
Explanation:
There are three types of purchase decisions which are routined, limited and extended.
Routined problem solving is when the customer realizes a need and buys a product he/she has bought in the past.
Limited problem solving is when the customer has some experience and makes minimal research to take the decision. He is familiar with the product and major brand and the features but doesn't have all the information.
Extended problem solving is when the customer gets all the information about the product and brands before deciding what to buy.
According to this definition, the case is an example of limited problem solving because Anne knows a brand and its features, she doesn't research more information about the product she needs and takes a decision based on that.
