It is possible to manually define the minimum price of the module that is shown to the user, through the "From Prices" feature. This allows the user to know the minimum price of a certain extension before selecting it, as shown in the picture below. For this, the module must have at least one published version.
Steps to define "From Prices"
Go to Cockpit
Click on Package Builder
Click on Modules
Select the module in which the "From Prices" feature will be configured
In the Module, click on the Miscellaneous tab
Click on Regenerate (update takes up to 10 minutes)
Click Save and publish the module
Automatic updates for "From Prices" are unavailable. To update From Prices for an extension module, use the Regenerate action described above, then save and publish the module.
