They usually say 3-5 days business days so I wouldn't include weekend on those days. If they shipped it on Thursday then you count Friday-Monday-Tuesday-Wednesday-Thursday. Don't know how to explain it better :sorry:
Mine from Japan was like that:
15/02/2012 Admitido
16/02/2012 Salida de la Oficina Internacional de origen
18/02/2012 Llegada a la Oficina Internacional de destino
18/02/2012 En tránsito
20/02/2012 En trámite de importación - Emitido aviso al Destinatario
The 18th it arrived to Spain.
Now I'm waiting for the budget I need to pay for Custom fees & handling that should arrive by tomorrow to my email.
