Most nonprofits hide retail value from bidders to avoid creating an artificial barrier to bidding. However, you may want to display the retail value for bidders seeking a deal.
In the Home tab, click the pencil icon next to the event name.
Uncheck "Don't display the retail value on my promotional flyers."
This setting applies to all flyers within an event. If you want some flyers to show the retail value and others not to, then check the box, and print the flyers for which you want the retail value hidden. Finally, uncheck the box and print the remaining flyers.
