Price history is not public yet
We keep earlier source checks internally so a new collection does not erase what was seen before. We do not publish individual changes until each provider's reuse rights and the change-detection method have been approved.
What is available now
249 published prices inside the 30-day window from 31 providers, out of 47 providers tracked.
Latest source check: 2026-09-27. The comparison window closes on 2026-10-27.
Why the detailed record is withheld
A historical number can be misleading if a package changed, a promotion ended, or the source page used different options. Publishing the full record also requires permission to republish each provider's price data. Those checks are not complete.
Next action: use the comparison, check the date beside the price, and open the provider's own page before buying. Individual history will appear here only after the method and publication rights are approved.
