Buyers are learners in that purchase decisions are not isolated behaviors. Buyer
behavior and purchase decisions are based on the relevant knowledge that buyers
have accumulated from multiple sources to assist them in making the proper choice.
Internally, buyers reflect on past experiences as guides for making purchase decisions.
When sufficient knowledge from past experiences is not available, buyers access external
sources of information: secondary sources of information (e.g., trade journals,
product test reports, advertising) and other individuals the buyer perceives as
being trustworthy and knowledgeable in a given area.
