Here’s the price comparison pro configuration:
Normally, if any of the prices are on sale, you would:
1) Have TWO CSS selectors for the regular price, one matching the price box with strikethrough on it on a product on sale page, followed by a comma, followed by the CSS selector for the price on a product not on sale
2) Then one CSS selector for the sale price.
