@mrsterryn I believe you may be some long lost relative. This thread seems very similar to another, “Oops need to fly to Tokyo to buy a bag”. After reading that thread and as I will be in Tokyo next week I have already set aside to visit a couple of shops in Ginza to look at a bag and watch that I do not need but like the look off. I suspect said items will return to Australia.

You have done your research and as
@Flying mermaid said, just go J. MrsM and MissM often convince me they have done research that shopping in the US is far better than AU. As I mentioned up thread we are both deluded.
