I've been 3 years in Vietnam now and I need a new Mac but can't buy it here. I need a BTO model. In July I'm going to Japan for a week and I'll stay at the youth hostel. Can I order in store and delivered to the store? As I don't have a Japanese Apple ID account (I have one from Canada), can it be ordered? If no one knows for Japan, can it usually be done in any country that has an Apple online store that takes BTO?
