On the struck-through price. We only strike a former price when it is the merchant's own recent list price for this exact SKU. A 90-day average is shown as a labelled comparison instead — never as a crossed-out price. Federal pricing rules (FTC 16 CFR § 233.1) treat a struck price as a claim that it was genuinely offered at that amount.

Current best price matches the 90-day avg. Chart starts at Jul 20 because that is the earliest observed point in this window. Recent range: $19.97 to $19.97.

Last observed 2026-09-22 05:00 UTC. Every point on this chart is a reading we actually recorded. We do not append a marker dated “today” to close the gap when our last check is old — that would put a date on a price we never saw. If the chart stops short of today, that gap is the honest answer.
