Making the Total Count Before Checkout
The final question is not whether a business may charge fees, sell add-ons, or bundle services. It is whether the price available when a consumer first compares alternatives is the price that can support a fair comparison. This series has examined that question through consumer reactions to drip pricing, the six-study evidence on optional surcharges, and the hotel resort-fee analysis of mandatory charges. The practical judgment is to make the comparable total visible before the first consequential choice, while preserving genuine optionality and keeping the limits of the evidence in view.
One price problem, three layers of choice
A delayed fee changes more than the amount displayed on a screen. It changes the order in which a consumer makes judgments. First comes an attention decision: which offer looks worth opening? Then comes a base-price choice. Only afterward does the shopper decide which add-ons to take, see the resulting total, and face the choice of completing the purchase or starting over.
That sequence joins three layers that are often discussed separately. The first is salience: the low base price is the number most available when alternatives are ranked. The second is processing: fees must be found, added, remembered, and compared with other sellers’ charges. The third is persistence: after the shopper has chosen an option, restarting demands time and effort and may feel like admitting that the first decision was poor. Seller incentives form a fourth surrounding layer. A hotel or platform may fear losing attention if it displays a complete total while rivals display only a base rate.
The six-study research by Shelle Santana, Steven K. Dallas, and Vicki G. Morwitz shows how these layers can combine. In one airline experiment, 54.5% of participants exposed to drip pricing initially chose the lower-base airline, compared with 11.7% when the optional surcharge prices were shown before the initial choice. After participants saw their add-ons and had an opportunity to restart, 36.5% of the drip group still ended with the lower-base airline, compared with 10.2% of the non-drip group. The drip group was also more likely to select the more expensive option given the add-ons they chose: 24.5% versus 7.8%.
These figures are not a claim that every consumer is fooled or that every lower base price is a bad deal. The lower-base option could be cheaper for someone who declined the add-ons. The point is conditional and more precise: when the price structure is arranged so that common add-ons reverse the comparison, delaying those prices increases the chance that the first number will continue to govern the final choice. The non-drip group also made mistakes, which is consistent with partitioned pricing and ordinary inattention. Upfront disclosure improves the decision environment without making it perfect.
The restart results add the most important connection. Participants in the drip condition were more likely to restart than participants in the non-drip condition, suggesting that some noticed the problem. But only 15.9% of participants restarted overall in that first experiment. Awareness of a worse total therefore did not guarantee a new comparison. The consumer had to value the possible saving enough to overcome the perceived cost of returning to the beginning, repeating choices, and reconsidering a decision already made.
The FTC’s economic analysis of hotel resort fees shows the same structure in a different setting. A comparison page may list room rates without resort fees. A hotel page may reveal the fee separately. A booking page may finally combine room charges, taxes, and the resort fee into a trip total. The total is present before payment, but the first page has already shaped which hotels receive attention. The traveler must then perform the comparison work that could have been done by the interface.
