Can it be cheaper to buy goldware in Hong Kong by using a UnionPay card? Or how can I make it cheaper? Is there any time period when there are discounts?

It is recommended to go to Chow Sang Sang and Chow Tai Fook stores

I have bought from these two stores, the price is much cheaper than in mainland China

And the purity and color are better than those in mainland China OK

If you go to Hong Kong to buy gold, use a bank credit card

The exchange rate is based on that day

Hong Kong gold changes based on the changes in the international gold price the day before

One price today may be another price tomorrow

As for other items, there will be big sales during Christmas.

It is recommended to bring some cosmetics and the like, and you can buy them near Times Square.
