Ok I'm probably being really premature here but I have never had any problems with USPS Express Mail service to the UK. I was expecting a parcel to arrive today using the Express Mail International with the guaranteed date service. According the USPS website the shipment left the US on Tuesday 9th Feb in the afternoon but since then nothing at all. I have received my express mail parcels in the past after 5 working days max, normally 4 but in this case the parcelforce UK tracking which would handle the shipment is not showing it's arrival in the UK. It actually scans the parcels as arriving in the UK before customs so I know it's not stuck in customs. Anyone with more experience care to share if they have experienced delays with the EMS guaranteed date service. It's the weekend now so I'm not sure when the UK website will update next and am a bag of nerves!!!
