Consumers selected round prices and/or sales-totals at greater than chance levels across two different pay-what-you-want situations and one self-pumped gasoline purchase. The differences among these situations suggest that the tendency to select round prices/sales-totals reflects a subjective preference (or liking) for round prices and not a variety of other potential explanatory processes. Discussion focuses on possible economic consequences of this revealed preference for round prices as well as directions for future research.
