This toggle switch controls the visibility of sale prices within your variation tables and carousels.
By turning it on and clicking the ‘Save’ button, you can display the discounted price next to the regular price when a product variation is on sale.

Doing so helps you create urgency and let wholesale customers use the Variation Table and see the value they are getting immediately.

Note: To see the table and sale price on a variable product’s detailed page, keep the Variation Table switch turned on.
