I would agree with Holdfast here.
As I live in Norway, I would prefer royal mail for most items and with an option for express shipping by courier (DHL or the likes).
The latter (esp. DHL) incurs some ridiculous extra charges for me in addition to the VAT but at the same time they are often 3-4 times as fast as Royal Mail. Royal Mail has the advantage that you can pick it up at your local post office and that you don't need to be around just for the delivery.
