But you are not a shop selling microwaves or anything else most likely or
you'd be out of business quickly. I suppose you might do OK selling gravel.
Virtually every retail establishment has costs which *do* vary with the
selling price of a unit. Which do you think sits on the shelf longer, the
$100 microwave "marked down" to $69 or the $399 unit? That shelf space
costs money, advertising costs money, heating, cooling and lighting the
store costs money. Sometimes the store has their own capital tied up in the
goods (not Walmart, it's yours until it is sold) and a higher profit is the
only reason for selling higher priced goods that take longer to shift and
sell fewer.
Do you really not see this?
