“…the average person treats a price ending in .99 as if it were 15 to 20 cents lower.”

The tendency is called left-digit bias, when the leftmost digit of a number disproportionately influences decision-making. In this case, even though the real difference is only a penny, research shows that, to the average person, $4.99 seems 15 to 20 cents cheaper than $5.00 – which results in selling 3 to 5 percent more units than at a price of $5.00"

Why Literally (Almost) Every Price Ends in 99 Cents

https://en.wikipedia.org/wiki/Psychological_pricing

EDIT: The left-digit bias is not just pennies / cents. It applies when going from $99 to $100…$399 to $400…$999 to $1000 etc.

EDIT 2: If you have a car for sale and you want $10,000 for it are you listing it for $10,000 or $9995?

    Devils advocate but I absolutely list my online prices at $XX.99 because people are more willing to buy from a seller who seems like a legit business instead of a private person. This is also why I make kinda arbitrary prices like $113.99 instead of something like $115 even.
