How can I change the prices/amounts visibility?
In Frequently Bought Together, you can easily show or hide the product prices and the total amount from the preferences page (How can I access the app preferences page?)
In the app preferences page, go to the Visual styles → Prices section. Here, you can configure if regular, sale prices and 'compare at' prices are displayed.

It is important to note that when discounts are enabled, both sale and 'compare at' prices are always displayed.
Below, you can find some configuration examples.
All prices displayed

Regular and sale prices displayed

Prices hidden

It's important to note that if you decide to hide all prices, all the original prices in the app will be hidden, including the total amount above the add-to-cart button.
