When Magda decided to buy a new computer, she thought about all the brands she could recall seeing advertised, but she would consider only those brands she could buy at her local Best Buy electronics store. The brands she considered represent Magda's "retrieval" set.

Explanation:

The retrieval set is the universe of options a subject has to evaluate as providers to satisfy his or her needs. It is especially understood as the universe of options the subject knows, not all of the universes that he or she has available. All the brands, providers, and distributors enter here. But not the products. It is only for institutions or organizations, not products, or objects.
