Mine took forever to reach the US which i think was the international mail service fault, believe they have to have so much weight before making trip across the Atlantic. It finally posted as yours did on Saturday. Usually they do update whole way. Ive seen them sit at ISC for up to a week or so. Sign up for instant email notification on usps site for your package and try to forget about it until you get notification. We got snow on Monday and today so im sure it will be alittle while until things get moving as usual.
