Set up an extra fee

Step 1: Open the option

In the option set editor, go to 1. Add options and click the option you want to add a fee to. Its settings open in the Content tab.

Step 2: Choose Extra fee and enter the price

Set Add-on to Extra fee, then enter the price:

Options with a list of values - in the Option values table, choose Extra fee and type a price for each value in the Add-on column.
Single-value options - in Option settings, choose Extra fee next to Add-on and type the price.

Can't see the Add-on column? Click the Columns icon next to Option values and turn on Add-on.

Step 3: Save and check on your store

Click Save.
Open the product page on your store and select the option. The extra fee is added to the price.

How customers see the extra fee

On the product page - you choose when the price appears in Settings > General Settings > Option type setting > Add-on display:
- After selecting option values (default): the extra fee is shown once the customer selects the value.
- Next to option values: the extra fee is always shown next to each value.
In the cart - the extra fee is shown next to the selected value, for example (+$5).
At checkout - the extra fee appears with the text Selection extra fee for {{Product title}}. You can rename this text in Settings > Translation Texts > Default text customization > Checkout page.
With Quantity - if the option uses Quantity, the fee is multiplied by the quantity the customer chooses (for example, 3 x $5 = $15).
