Prices the Meta Store charges in each currency, not conversions from USD. A currency not checked in the last 3 days is left out. Lowest tracked starts in November 2024. Outside USD, few or no prices were recorded from July 2025 to October 2026 (January to October 2026 for CAD), so sales in that period can be missing.
