Add-charge for specific variants

While you create options in the Options (Step 1), you will see a pop-up window for Option detail.
In the field "Option values", find the value you want to add charge and fill the desired extra price.
In this example, I want to add $2 for the medium-size picture and $4 for the large-size one.

If your default currency is USD, it will be 2USD and 4USD additional charges.
Finally, click on Save.
