Watch this price

We 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 — 3 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: we have recorded 2 changes.

Every change we recorded at Amazon

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 8, 2026 · 3 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.

Prices we recorded ourselves. Usual is the price on the typical day, with limited-time deals left out unless they ran on most of the days we recorded; Average is the mean of every recorded day, deals included, so a gap between the two columns is a record holding an outlier.
