You can find the button confirm receipt in the My Orders section.
Once the item is marked as "received", you can rate the seller.
By confirming the receipt you release the payment to the seller.
Please note: If the seller sends the item as a insured package with the shipping label of Prelved, our system will recognize that your parcel has arrived via the tracking system. However, this does not happen in real time. It may take a few hours before your package is automatically marked as received.
