How to Add Price History to Osclass Listings
Price history can add marketplace transparency when it records real listing changes and keeps the current price separate from historical data.
Price history is a record, not a price recommendation
A listing price history should answer a simple question: how has this seller changed the advertised price over time? It should not imply a market valuation unless the site is actually calculating one from comparable listings.
Record meaningful changes only
The useful data points are actual price changes with their dates. Re-saving a listing without changing its price should not create noisy duplicate entries. The current listing price remains the authoritative value for purchase or contact decisions.
- Store the previous and new price when a change occurs.
- Keep the original currency attached to the history.
- Display dates clearly and in chronological order.
Use history to improve buyer confidence
On marketplaces where negotiation and price changes are common, a visible history can help buyers understand whether a listing has recently been reduced. For administrators, the same record can help explain changes reported by users.
