Price Presentation Psychology

When dollar amounts are presented as round ex. $XX.00 - people think about how much profit you are making, or that the price is negotiable, like a flea market or tradeshow…

When one presents $XX.99 / $XX.49 - people think about what a deal they are getting, and do the mental math on rounding the number.

In very RARE situations, is a rounded number ever better.
