Clara has a designer jewelry business that targets high-income market segments. Her jewelry is very distinctive, and she sells is online to clients all over the world. Clara's high price points for her earrings, rings, pendants and bracelets come from doing all of the following EXCEPT: a. Using the strategy of "market skimming": price high for margins, not worrying about volume. b. Using high prices despite no real difference in quality. c. Determining customers' willingness-to-pay, then price right below that sensitivity point. d. Using prestige or status pricing: price high for image appeal
