But that means the recipient has to be in to receive the parcel. Just had a purchase sent this way, and the sender did not add the tracking number so I had no idea when it would come. A second purchase was sent by RM Tracked 48 which does not require a signature. I was given the tracking number, so knew when it was going to be delivered and, as we were not going to be in, was able to update the delivery to leave in our safe place (rear porch). The second class signed-for parcel cost £4.69 whereas the Tracked 48 cost £3.29. I definitely prefer the latter as a receiver, and send all my sales that way too. Tracked 48 has £150 compensation, compared to £50.
