Here's what Luggage First is telling me:

"Please be advised, we are aware of the ongoing customs strike in Greece.

Please be reassured that I am personally in contact with senior agents of Fedex/Customs in Greece, who are doing everything possible to ensure that this is delivered well before our delivery commitment of Monday 6th October.

Any delay experienced, I believe will be slight and of little significance and I expect this to be safely and promptly delivered.

I will keep you updated of the progress of your shipment."
