I just had three shipments from the UK, none of them took anywhere near 14 days.
Sweater by Royal Mail/ US Post: 30Jan -1 Feb
Sweater by Royal Mail/ US Post: 14 Feb -19 Feb [18th was a postal holiday]
"large gift basket" by Fedex: 14Feb -15Feb held for ransom in Memphis, 16 Feb ransom paid, @ my door 18 Feb.

They just state "14 days" in case it fall off the airplane and gets shipped by slow boat via China .

Back on the main topic I would agree as others have said that Saltaire [sp?] may be a bit OTT for St Patricks day.
