Compare-at-Price shows your customers the original price of a product in comparison to the sale price, unlike the Quick Compare add-on that compares different products.
The sale prices are set manually on individual products without the use of discount codes.
When announcing a price reduction, make sure you comply with the laws and regulations for your business and the markets or regions you operate in - such as the European Economic Area (EEA)
If Compare-at-Price is not working correctly, check the settings applied for the region.
