Go to AmazonWe are not ready to call this price.
We check at least every 12 hours and hold a day-by-day record of what this cost — 0 days of it so far. Calling a price high or low needs 7 of those days and at least one change, because a range needs two prices: this one has not moved since we started watching.
Every change we recorded
Every row is a price we saw change. We write one only when a price actually moves, so a gap here means the price held.

Price history
Tracking since October 10, 2026 · 0 of 7 days to a verdict
We do not draw a chart under 7 days of record. Over a handful of days every product is trivially at its lowest recorded price, and a chart that says so is worse than no chart.
