For me, my luxury purchases have shifted to things I can still wear (jewelry) and away from things I no longer need (shoes, handbags, coats, dress and work clothing) for the time being. I'm ok with that. But it does seem wrong for people to pay more in one part of the world than another for the same things!
It was always the case, as somebody who traveled frequently for business, I knew exactly what to buy in which city/country in the world, it has a lot to do with taxation and transport, some things you can buy for close to half the price in the US, especially in places with a low VAT, other things, often if it is made in the country, the government tries to encourage local products and the local economy, so obviously as a buyer you could take advantage. Often the flight ticket would cost more, but if you are there anyway....
