SaleTag keeps sale product tags up to date automatically. When a product has at least one variant with a price lower than its compare-at price, SaleTag adds your chosen sale tag. When the product is no longer on sale, SaleTag removes that managed tag.Use sale tags to power automated collections, admin filters, storefront labels, or other workflows without manually checking every product. SaleTag does not edit prices, create discounts, modify themes, or change checkout.
