Yes, but you can buy repeated interactions. What's the actual difference then? IMO it's down to arguing semantics about how "tight" is the causal chain between the cause and effect. Do you perceive the cause (repeat buying) and its inevitable effect (caring) as sufficiently distinct in time and space? Then I guess you didn't buy the caring, you "built it through repeated interactions". I personally see that boundary as mostly linguistic, and tend to not draw the distinction.
