Why every price ends in 99
$9.99 is not one cent cheaper than $10. It is one whole digit cheaper — and the digit is the part you actually read.
Intuition test — answer before you read on
Why do luxury brands often price in round numbers instead of ending in 99?
$9.99 is not one cent cheaper than $10. It is one whole digit cheaper — and the digit is the part you actually read.
What everyone sees
An odd, slightly grubby price that everyone claims not to fall for.
What is actually happening
Two effects run at once. Left-digit anchoring means the leading numeral does most of the encoding work: 9.99 is filed near “nine”, not near “ten”. And decades of retail conditioning have turned a 99 ending into a discount signal in its own right, which is why premium brands avoid it and price at round numbers to signal quality instead. There is also a historical accident in the mix: odd pricing forced cashiers to open the till and make change, creating a receipt and reducing theft.
Why it stays hidden
Because it survives disclosure. Knowing about left-digit anchoring does not stop the leading digit from arriving at your eye first.
