Drip pricing (DP) is distinct from partitioned pricing as it sequentially discloses surcharges to consumers. Critics see DP as a deceptive pricing tactic because it obscures the final price of an offer. We examine the effects of the timing of the final price disclosure and the number of sequentially presented surcharges on consumers' attention to the final price and, ultimately, perceived price fairness. In an eye-tracking study with 225 participants, we find that the sequential (vs. up-front) disclosure of the final price lowers perceived price fairness by increasing consumers' attention to the final price, in particular, when the number of surcharges is high. In addition, the sequential disclosure of the final price lowers perceived price fairness because of higher perceived price complexity and lower pricing transparency perceptions. The findings suggest that firms need to be aware of both attentional and cognitive effects of the final price disclosure when designing DP.

For example, partitioned pricing (PP) tactics, that is, dividing the total price of an offer into a base price and mandatory surcharges, are particularly popular in many services and retailing contexts (e.g., Abraham & Hamilton, 2018; Morwitz et al., 1998). Furthermore, customers now often face drip pricing (DP; Ahmetoglu et al., 2014), which is a pricing tactic in which firms advertise the base price of an offer up front while several additional charges sequentially "drip" in after the initial choice. Whereas price bundling integrates different products or services (e.g., Li et al., 2018), DP disentangles the price components of an offer to make it appear less expensive. DP has become popular in industries such as transportation, hospitality, and financial services. Firms may use DP for two major reasons. First, firms may advertise their offer at a low base price and then sequentially add mandatory fees, suggesting a deal up front (Seim et al., 2017; Shelanski et al., 2012) and thus obfuscating the real final price (e.g., Chioveanu & Zhou, 2013). Second, they may want to make single price components salient to attract their customers' attention. For example, showing a fairly high price for on-board meals might positively affect the customers' quality perceptions of an airline (Bertini & Wathieu, 2008). In addition, increasing the salience of surcharges and cueing them to an external locus of causality (e.g., a tourist tax) can influence customers' blame attributions in case of a price increase (Pallas et al., 2018). DP has become a concern for regulators around the world. Consumer protection authorities such as the Federal Trade Commission (FTC) have criticized DP tactics, urging firms to disclose mandatory surcharges "immediately a...
