On the other hand, the difference between the average price of a good purchased in a market or a bazaar, where such bargaining often occurs, and the price of the same good sold in a different type of retail outlet, such as a department store, should normally be treated as reflecting differences in quality due to different sales conditions.
Preisdifferenzen auf Märkten, auf denen normalerweise gehandelt wird, wie etwa auf einem Basar, werden dagegen den Verkaufsbedingungen und somit der Qualitätskomponente zugerechnet.
