How often this price moves
We check this product on every sync and record whether the price went up, down, or held. Not how much: only which way.
This price has not moved once in 18 checks. Amazon has held it steady for the whole time we have been watching.
How this is measured
Each bar is one sync, oldest on the left. Bars show direction only, never amount, and all are the same height for that reason: we record whether a price changed, not what it was. A move under 1% counts as held. We do not keep price history, by design. See our pricing data for the method.
