Although a considerable amount of research has investigated consumer knowledge of individual prices, consumer knowledge of marketer pricing tactics (e.g., partitioned prices, pennies a day) has received only limited attention. In the current research, a model depicting hypothesized antecedents of consumer knowledge (both accurate and self-perceived) regarding pricing tactics marketers use is proposed and then investigated in two studies. Tests of the model provided support for the hypothesized antecedents of both objective and subjective pricing tactic knowledge and suggested that experience is a key moderator of the objective pricing tactic knowledge–subjective pricing tactic knowledge relationship. © 2007 Wiley Periodicals, Inc.
