Characteristics - from price

You have several things:
1. In the associated module of your menu (you can access it via the menu Display->Content module and then edit the module with the id 95), you can change the way prices are displayed with the "Price display method" option. Otherwise, you can also set the prices on your main product for the price that you want to display there.

2. You can change the text around prices with translation overrides:

However, that will modify it everywhere.

3. You could edit the file "listing_price" of the view "product" via the menu Display->Views to suit your needs.


So you could for example display the prices as a range and then add an override to have a separation text between the min and max prices.
