Prices like 9.99 are so common that they seem natural. But they exist because they can influence how we perceive prices.

At the same time, luxury brands often avoid them entirely.

The left-digit effect

People tend to focus on the leftmost digit of a price. 4.99 can feel closer to 4 than to 5, even though the difference is one cent. Studies have found this effect in several markets, though its size varies.

Signalling a bargain

Prices ending in 9 have become associated with discounts and value, so shoppers may perceive them as sale prices.

Prestige pricing

Round numbers can signal quality and simplicity. Upmarket restaurants and luxury brands often use round prices to avoid associations with discounting.

Other pricing tactics

Decoy pricing: adding an option designed to make another look better value
Bundling: combining products to obscure individual prices
Price partitioning: splitting costs into base price plus fees

Being a smarter shopper

Round prices up mentally and compare unit prices rather than headline prices.
