I just checked on an item purchased from a UK seller on 12/28/10 (small item able to ship in an envelope), and he immediately reported back that weather in the form of snow has been delaying delivery times to the USA.
Also purchased a saddle from a French seller on 12/10/10 that never arrived, so the seller refunded my purchase price, but I really was looking forward to receiving the saddle. Who knows, it may show up, but not holding my breath.
WIth all the snow delays/shutdowns at NY/NJ airports, suspect that is playing a big part in the slow delivery also.
Would recommend checking directly with the seller first to check the shipment status. Both sellers I contacted provided prompt and courteous replies.
