Because shops can benefit from it. For example, the gold shop will charge a discount fee according to the grams. The greater the grams, the more you receive; Sometimes, some inferior products may be used as gold to deceive consumers.

First, there will be a discount fee. If she takes the old gold jewelry to the gold shop for exchange, she will charge a certain discount fee. About 30 yuan per gram. If you have 10g jewelry, then the depreciation charge is 300 yuan. And there will be a lot of wear and tear. For gold and silver jewelry of non-big brands, gold shops do not calculate by weight, but melt old gold jewelry and convert it into gold according to the final weight of gold. In this process, there will inevitably be some wear and tear. If the gold necklace of14g is replaced with gold ornaments of less than10g, it will be greatly discounted.

In the process of trade-in, it is inevitable that some dishonest merchants will use defective goods or others as thousands of gold, because the environmental processing fees and technical fees are very expensive. The store said trade-in, it won't really give you an identical one. In fact, all he gave you was low-purity gold. Moreover, when you exchange them, you have to pay for the new gold jewelry technology. She basically doesn't change a gram, which is very expensive, sometimes ranging from tens to hundreds. Therefore, gold shop owners do not suffer from old problems.

But consumers have no discrimination at all, which will cause huge losses to consumers. So remind everyone that to participate in the trade-in activities, you must sign an agreement with the merchants to indicate the weight and grade of video quality. Even if there is a fraudulent agreement, it is convenient to safeguard your legitimate rights and interests in the future.
