If the price of the item you are delivering has changed, it is important to notify the buyer immediately. The buyer may find an alternative link to the item at the appropriate price. If you cannot find the item at the requested price, it is better to cancel the delivery on your part so the buyer can cancel the deal and create a new one with the updated price or create a new order for the missing amount. It is recommended to purchase the item as soon as possible to avoid further price changes.
