In addition to the above algorithms Baťa pricing can be enabled for each listing. Baťa pricing is a method of psychological pricing which rounds the calculated price up to the nearest 99¢. If rank cannot be preserved by ending the price in 99¢ it will end in 9¢ instead. If ending in 9¢ is also not possible the final price will be the same as originally calculated by the chosen algorithm. Default behavior will use 99¢ but this number can be configured from the "Behaviors" page.
