Content Egg can save the price change points to its own database. Go to
Content Egg > Settings > Price alertsand make sure the
Price historyoption is checked.
Each time the product is updated, the plugin will save the values of the old and new prices to its own database. Then, you can display the history of price changes using special general shortcodes:
This shortcode will display data for the cheapest product on the page.
You can also use module shortcodes to display a specific module's data, for example:
[content-egg module=Awin template=price_tracker_alert]
Since the plugin uses its own database, the chart can be displayed only after several price updates.
Please note that Amazon's rules prohibit historical price data from being displayed. As such, we don't recommend using this feature for the Amazon module.
