How we treat stale prices

We check every retailer 12× a day and stamp each listing with the time we last verified the price. Fresh means < 6h old. Verify means 6–24h, we still show it so you see the full retailer footprint, but click through to confirm the live price. Stale means >24h. Likely changed. Anything older than 30 days is hidden entirely.
