There is a 20% handling fee for brand-name jewelry replacement, because old jewelry will be worn out.

General jewelry stores will have this trade-in rule.

For example, there is a 20% increase in the price of freely convertible gold, that is, the old gold price is exchanged for the new gold price, and the purchase price of the old gold is plus 20%, for example, the old gold 1 000 yuan. Now we need to make up for 200 yuan and exchange it for a gold jewelry from 1.200 yuan.
