I was sceptical about using this service but have used it 3 times now and it’s pretty easy to use. Update : Changed from 5 to 3 stars as posted on 5th and only picked up by the courier on 10th! Very slow.
Another update! Changed to 1 star! The recipient has been advised they will receive their parcel anytime between now and 2nd Jan! For a package posted on 5th! Wont use again after this.
