I will give you an example of price-taker about the air travel industry,we notice that there are different airlines that supply flight favors from one destination to the other. The essential fare for all these airlines would be nearly comparable. The diversity could get in the form of another favors like as food and preference check-in etc. when one airline is charging extremely amount more than its peers for the same grade of outputs, people would just purchase tickets from the lower-of cost airline.
