Ditto for Dave,
Worked in a computer store, work now as a professional.
Over the years I was working in the store (1993-1999), there were always people who would pay say 5% more, because they felt that they were getting the attention and the experience of an expert even if we were 23-27 years old.
But their number kept lowering over the years, because the majority of customers was simply adding up numbers and finding a lower total sum elsewhere.
