The strike-through 'was' price shown next to a sale price.
Compare-at price is a secondary price field on every Shopify variant. When it is higher than the real price, most themes render it struck through to signal a discount, and Google Shopping populates the `sale_price` and `price` fields accordingly. It is not a scheduling primitive — Shopify does not automatically clear it when a sale ends. Legal frameworks in the EU (Omnibus Directive), UK (ASA guidance) and several US states require the compare-at value to reflect a genuine prior selling price, usually the lowest price charged in the 30 days before the promotion. Setting it artificially high to inflate the perceived discount is considered a misleading commercial practice.
