The discount here is quite satisfactory, and some goods in less famous gold shops are as low as 5.5 fold. If you are not in a hurry, you can get to know it slowly. The price in Sasa is the same as that in Hong Kong, but the difference is that it is denominated in Australian dollars, and the UnionPay channel takes a credit card, which is quite cost-effective, equivalent to a 10% discount on the original price.
