Method and provenance

Recorded via weekly Sunday readings (parent ASIN, series began 6 October 2024); for collection rules, signal thresholds and offer constraints, see our Methodology.

The child ASIN supplying this family's metrics changed during the observed window. Readings either side of that change are not strictly comparable, and no trajectory claim is made across it (§6.1).

This product's rank window contains a week with no recorded offer. A rank movement across a gap in availability is not evidence of decline, so no decline claim is made from it (§6.3).

Data source Market data retrieved via the Keepa API (dated observation: 17 October 2026, not live Amazon prices); for collection rules and continuous granular history, see our Methodology and keepa.com.
