This research investigates the influence of package and price on perceived quality under the chocolate brand which not yet sold in Taiwan. Comparing the perceived quality before and after aware of the commodity price investigates whether the exterior package and price affect the consumer's judgment on the product quality without knowing the brand name. This research takes two subsequent experiments and collects data from the questionnaires, and completes the investigation which is directed against Taipei consumers. The findings show that (1) being not familiar to the brand name, moreover not knowing the price, the participant can merely judge the quality from the exterior package of chocolate. Thus and so, the participant makes the different quality judgment through the different exterior package. (2) As soon as knowing the chocolate price, the participant changes the quality judgment immediately. The implications of research findings may help the importer and retailer to draw up the exterior package and price strategy.
