If you are posting an item we recommend using a courier services for all your rentals. We also recommend you include the return postage satchel in with the item when you ship it (you can ask for compensation). That way you can fill out the satchel, so you know the correct information (address) is written down, and also take note of the tracking number, to ensure your item is not only posted back, but can also be tracked should it go missing. If no tracking number is used, the parcel cannot be confirmed to have been sent or delivered, and cannot be tracked should something go wrong! Without a tracking number, the sender of the parcel is liable for it’s loss.
