How Options with Costs are Displayed on Product Pages
When your theme snippets are installed for the pro tier, Product Customizer will display pricing changes on the product page.
For options that have a price for "completion" (single-line text, paragraph text, file upload), the price for entering the option will be displayed next to the label.
For options that have a price for a "choice" (dropdowns), the price is displayed next to the choice to which it relates.
A "Customizations" total is displayed on the product page below these options.
