Clickaparcel - a very reliable courier service.
I chose the DHL48 option. It was picked up in the morning and reached its destination the very next day, despite snow! The realtime tracking did not appear on the clickaparcel site until after the delivery but was very detailed when it appeared. I could, however, track the parcel through DHL with no problems. Very affordabel and a fraction of DHL's prices when you use them direct. Excellent service.
