EU prior price

If you sell to the EU, an announced price reduction should be measured against the lowest price of the previous 30 days. Store Steward records the lowest daily price of each product for 30 days. When you simulate a public code, it warns you if a product’s current price is above its 30-day low, because an advertised “X% off” could then overstate the reduction.

This is a warning, not a block. Turn it off with Settings, “Show EU prior-price (30-day lowest) notice”. Price history starts when the plugin is installed, so the warning becomes useful after the first 30 days.
