extended problem solving

Explanation:

A situation where a buyer is buying a product he or she has never bought before hence requires considerable efforts, such is termed extended problem solving. The reason is that a buyer does not have prior experience about the product or the supplier, thereby creating complex buying decisions.

Here, buyers search for all available information inorder to choose among brands of products they intend to buy; being the first time of purchasing such.
