How to prevent online shopping from buying fakes?

First of all, don't blindly believe in the credit index, which is not an indicator to measure the authenticity of products. When we go to Yi Bei or Taobao, we will find the credit indexes of shopkeepers, some of which are blue diamonds, which means there are many favorable people! And many people, including myself, also use this as the evaluation standard, but later I found out that this is all wet! Why? Nowadays, speculation on credit index is popular on the Internet, and many people open many stores. Anyway, they are full-time to do this, and they have plenty of time! 1 month down, has arrived at the blue diamond! Also, many people have 100% favorable comments. In fact, how is this possible? I once bought a DD and gave it a medium evaluation. The seller called me, asked me to withdraw the evaluation, and gave me a return service! Second, don't be fooled by low prices, don't trust Hong Kong goods and Taiwan goods! It makes sense that online products are cheap. Why? Because we didn't rent a store or hire a helper, the product cost was reduced and the product price was naturally low! Think about it, how much did the products go to the counter, how much did they pay in the mall, and how much did the waiter pay every month! However, everyone should pay attention to products with ridiculously low prices. Without the slightest temptation. I'm sure 100% is a fake! Because many sellers make Hong Kong goods and Taiwan Province goods ... However, there are many tricks in these products. More than 50% of the products are imitations processed in Guangdong, and the quality needs to be verified. Even those sellers are not professionals, why should they promise the authenticity of the products? In fact, JM who has been to Hong Kong or bought DD in Hong Kong knows that the price is not 30% cheaper than those boasted by online sellers! Third, online sellers say that foreign countries get goods directly! You know, foreign countries use euros or dollars, and unless there are formal channels, you can't get cheap prices! Even the Korean Lan Zhi Sleep Mask is about 120, but many sellers have offered the price of 1 10. Isn't he making money? No way! There's something wrong with this! My classmate bought a bottle of NEVEA Toner in France, 10 Euro. It's just Nivea, which is a poor brand in China. You can think of other brands, and don't trust foreign goods. Meanwhile, do you know how much the freight is? Domestic express delivery prices are very expensive, not to mention foreign purchasing! In short, JM who buys DD online must be careful not to be deceived. After all, this DD is rubbed on the face! So, what should MM who wants to save money and MM who wants to buy online do? I suggest that you can choose products with QIC logo and Chinese and English instructions. Why? I don't know if you paid attention when you went to the store counter to see the products. There is a small label with the same security mark. I looked at it carefully that day, and it said QIC. These two descriptions are all products that have passed customs declaration and inspection by the State Quarantine Bureau when some foreign traders come back from abroad. Generally, this kind of dealer supplies goods to counters, and the products are reliable. As we all said, products that pay taxes are naturally more expensive than Taiwan Province goods, but they don't go into shopping malls. You know, it costs a lot of money to enter the mall! Because it is sold online, it may be a little more expensive than Taiwan Province goods and Hong Kong goods, but the price is far from that of shopping malls. After all, there is quality assurance, so it will be more reassuring to use! You may still have questions. QIC logo and Chinese description can also be forged. Then JMS can get the product and go to the mall. You can tell the waiter when you bought this product here. It feels wrong. It feels fake. The waiter will definitely take it out for your appraisal. You can smell the same products, smells and materials in the counter ... If you are not at ease, you can go through the inspection authorities, who will help you check the authenticity of the QIC logo and Chinese description. I think, then we don't have to worry.
