Hi,
You didn't provide your Joomla version number (although we ask for it when you create a new thread). So I assumed that you had the latest version and provided an answer adapted to that.
But with the screenshot, I can see that you're using Joomla 2.5.
With Joomla 2.5, you need to go in the menu Components>HikaShop, then use the "Display>Content menus/modules" menu of HikaShop. There, you can edit your menu/module and see its options, including the one for the display of the price or not.
The "HikaShop Default Menus" is where HikaShop create default menu items related to the display of HikaShop pages so that you can move them to your main menu if you want to. By default the "HikaShop Default Menus" menu items are not displayed on the frontend so that way, we can preconfigure menu items for you during the installation of HikaShop without changing your website frontend in the process even though your shopping isn't yet configured.
