Reduce the Left Digit By One

Use “charm” prices (e.g., $2.99, $49.95) to reduce the left digit as much as possible.

Overview

Your brain encodes prices before you finish reading the numerals. Therefore, a one-cent difference between $2.99 and $3.00 can feel like a one-dollar difference:

...while evaluating “2.99,” the magnitude encoding process starts as soon as our eyes encounter the digit “2.” Consequently, the encoded magnitude of $2.99 gets anchored on the leftmost digit (i.e., $2) and becomes significantly lower than the encoded magnitude of $3.00 (Thomas & Morwitz, 2005, p. 55).
