LowCostDrugs.com is a online drugstore. Recently, the company used a computer program to analyze the purchase behavior of customers sorted by zipcode and found that customers in some zipcodes are, on average, less price-sensitive than the customers in other zipcodes. Accordingly, the company has raised prices by 3 percent for the customers in the less-price-sensitive zip codes. Note that zipcode is automatically identified when a customer comes to the company's Web site.

Based on this information answer:

Is it ethical, for LowCostDrugs.com to charge some customers a higher price based on its analysisof prior purchasing behavior?
