The purpose of this study was to conduct survey of 237 Korean domestic consumers and 32 flower shop sellers to investigate the consumer perceptions and satisfaction with the use of open price systems in flower shops and suggest effective open price systems for Korean flower markets. The price of a cut flower and the packaging methods, were found to be the most important purchase decision factors by consumers and sellers. Consumers were more aware of the benefits of open price systems for cut flowers in a flower shop than sellers, and both consumers and sellers agreed that open price systems could help consumers’ reasonable cut flower consumption price reliability the most. Although the consumers had no objections to the open price system, sellers cited that daily fluctuation of cut flower prices (4.25), the ambiguity of open price system standards (3.78), and the inconvenience of open price systems (3.69) as objections to using the open price system. According to the survey of effective open price systems in a flower shop, consumers preferred to buy cut flowers in a bundle (3–4 stems) rather than a stem or a bunch, but the sellers had no preferences for the selling unit. Both buyers and sellers preferred the vase making as the best method of price indication. Consumers were more satisfied with open price systems of cut flowers higher than sellers expected (p < 0.001), with cut flower price (3.97) being more satisfied than cut flower quality (3.75). Overall, open price systems for cut flowers would improve consumer trust and satisfaction with cut flower prices, assisting in the activation of the Korean domestic flower industry further.
