Product card: Price History tab
See every selling-price change for this item, old price versus new.
Open Price History
On the product card, tap the Price History tab.
Compare old and new
Each row shows when the price changed, the old price and the new price, so you can see how pricing moved over time.
Note non-price events
Some rows mark events like 'item edited' or 'imported' rather than a price change — these won't show a price up/down arrow.
