1, the price is subject to the market price of Shanghai Gold Exchange all over the country, and the bank plus 10- 15 yuan. If you buy it from me, it can be cheaper, but you need to mail it, and the cost will be checked again.
2, quality, now gold bars are pure gold. If you want to buy, try to go to a bank or a gold shop. Don't go to some small broken shops, it's easy to be cheated.
The problem of the bank is that although the bank said it would leave you a certificate, it can be cheaper if you don't leave it. But this is equivalent to the bank selling your gold to others without you knowing it.
The gold bars I sell here have quality certificate and repurchase certificate, but I don't know anything else. I hope this helps.
