Products without own price

Hello,

As Food Store is WooCommerce dependant, you can use any function that works with WooCommerce for certain requirements.

In this case, you can hide the price if Zero using WC filter. Please check this link,

Otherwise, you can do the templating of Food Store plugin and modify the price HTML as per your need.

Thanks & Regards,
