No retailer we track is showing a price we can publish right now. The history below is still ours and still true; today’s number is not.

Amazon last quoted a price 10d ago, and their licence lets us print one for 24 hours. We asked again 3h ago and the answer came back without one.

Check at AmazonTell me when it is back

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 — 23 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 1 change.

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.

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