Odd pricing, also known as psychological pricing, is a marketing strategy used by businesses to leverage the psychology of prices to increase sales. By setting prices ending in odd numbers, such as $49 or $29, businesses can create an impression of a lower and more attractive price point than if they had used a round number such as $50 or $30. Moreover, research shows that customers perceive this type of pricing as being more honest and reasonable. Ultimately, odd pricing can have a positive effect on profitability, allowing businesses to boost sales while still seeing a return on their investment.
