The Longevity Gear Price Integrity Report
What we learned verifying prices on 354 longevity products: how fast published prices rot, the five ways they break, and the corrections we caught, with dates.
The state of the catalog (live figures)
Every price on this site carries a dated verification. As of 2026-08-16: 354 verified products, 71% re-verified within the last 30 days, 92% within 60 days, median verification age 3 days. We re-verify against the brand's own storefront data and flag divergence for human review; anything we cannot verify stays marked with its last-checked date.

The five ways published prices break
Stale MSRPs. A price verified once and never re-checked. The web is full of 2024 prices on 2026 pages. This is the default state of affiliate content.
App-discount divergence. Storefront data feeds report list price while a discount app rewrites what buyers actually pay at checkout. The feed is technically true and practically wrong.
Restructure jumps. Brands reposition (new SKUs, new tiers) and the old price range becomes fiction overnight.
Sample-variant traps. Automated price scrapers ingest $3 sample sachets as if the product price collapsed. Untended automation creates its own errors.
Quote-gated pricing. Premium brands hide prices behind consultations. Honest coverage marks these as estimates instead of quoting a number nobody can click to.
Corrections we caught (the receipts)
Methodology
Prices are verified against each brand’s own storefront data (product feeds and rendered pages), never aggregator summaries. Subscription pricing is recorded with its cadence. Quote-gated products are marked as estimates. We compare current storefront data against the last verified price and flag divergence beyond safety thresholds for human review before anything publishes. Amazon-linked products are excluded here: their prices are never scraped or cached, and readers check the live price on Amazon. Verified price bands across the catalog: the Longevity Gear Price Index.
