This study explores the pricing differentials between organic and ordinary products by telephone survey and on-store price recording. Season-specific and crop-specific price differences were examined to unveil the reasons for the price differentials. The survey showed most respondents are willing to pay a 10%~30% premium for organic products. In terms of season's effect, the price differentials in spring are far beyond general consumers' expectation, while that of summer and winter are relatively fair. Overall, organic leaf vegetables have an unexpectedly higher price than ordinary vegetables. It is suggested the long-lasting pricing strategy of organic products be modified to fluctuate according to market rules to reduce the general price perception of organic food. For example, the general produce price in spring should be decreased, while that in summer should be increased.
