Bought on

At $31.97 we would not have told you once since Sep 14. The lowest we recorded was $31.98.

A notification carries a button that stops that alert; blocking notifications for this site in your browser stops them all.

We are not ready to call this price.

We check every 3 hours but write a price down only when it changes, and we publish a verdict once 10 different days carry a recorded price. This one has 1, so how soon depends on how often the price moves, not on how often we look. If it is still $31.98 on September 28, this box will say so — a price that has held for two weeks is an answer too.

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.

Prices checked every 3 hours. “Held for” is how long that retailer has been charging this price. A hidden price is one we cannot re-confirm recently enough to publish. Delivery is counted only where we have read the retailer’s own figure; where we have not, the total says so instead of assuming it is free.

We earn a commission on purchases. It never affects our rankings.

The evidence

One line: the best price any tracked retailer charged, per day.

Tracking since September 14, 2026 · 1 observation

We do not draw a chart under 10 observations. With four data points every product is trivially at its lowest recorded price, and a chart that says so is worse than no chart. Check back once the record is long enough to mean something.
