Best places to travel when buying?

I don't know if there is a "best" and it will probably vary depending on where you're from. But I got (what I thought) was a good deal on a FOIS in Madrid last fall returning to the US, what with the exchange rate and getting the VAT back. I'm currently in Mexico but it doesn't look like there are any good deals here. Fiance and I looked at Omegas, Breitlings, and Heuers (she briefly indulged a Rolex fantasy). Without spending time haggling, prices are roughly the equivalent of no sales tax (8.25%) from a local AD. Not enough to entice me.

I originally titled this "best places to buy when travelling" but maybe it's the other way around. Where have you found good deals and where should I vacation next?

China

You will be able to find tons of great deals in Japan, easily.

Just came back from Japan. You'll have to look pretty hard for those deals.

Vintage, not so much. Tons of discounters for modern, though.

I think with a weaker pound you can find good deals in the UK especially on Rolex. Once you get a good chunk of the VAT back you’re in pretty good shape. Of course their Rolex selection is just as limited as the rest of the world but if you’re looking for something outside of a stainless sports model you might find a good deal.

I was just in India and the prices were ok. At the airport in Mumbai the salesperson told me they had “special deals” on Omega and without me even asking he was offering 30% off. Of course they’re marked up beforehand so basically you’re getting 15-20% off.

Duty free at most airports eg T5 Heathrow

Wow, you think the Pound is weak. Not where I come from. If the price of luxury goods wasn’t jacked up so high, based on exchange rate alone Australia would be a good place to buy for a visitor, especially as you can get a 10% GST refund when exiting the country.
