First of all, be wary of illegal transactions on the Internet. In the current online transactions, there are many behaviors that violate the relevant laws and regulations of the state, mainly business behaviors that require special permission from the state, such as online medical information, medical devices, online lottery sales, online securities trading, etc. It is difficult for consumers to get effective relief for the losses caused by engaging in such transactions. Therefore, consumers should identify themselves when shopping online, and should first pay attention to the legitimacy of the transaction itself. Second, pay more attention to the "blacklist" before online shopping. Online transactions are naturally virtual and uncertain, but consumers can also make full use of the Internet to quickly obtain information and understand the basic situation of sellers, among which it is very necessary to pay attention to the "blacklist" published online. At present, third-party trading platforms such as Taobao and Online Trading Guarantee Center have formed a "blacklist" of websites with bad credit records or infringing on consumers' rights and interests according to consumers' complaints and reports, and updated them in time. By paying attention to the "blacklist" information, consumers can not only avoid online shopping being cheated, but also keep abreast of typical fraudulent behaviors that have infringed on consumers' rights and interests. Third, beware of the low price trap. Compared with traditional real shopping, online shopping has the inherent advantage of low price, but the low price is limited, and the low price may hide a trap. In online transactions, criminals often take advantage of consumers' psychological characteristics of "being greedy for small things and getting cheap" to attract consumers' attention by giving away free gifts, "killing seconds" and other low-priced behaviors, and then make consumers fall into the trap and suffer losses by "fishing" and asking for payment in advance. Consumers should pay attention to identify formal online promotions, discounts and fraud, and don't blindly pursue low prices. Fourth, identify the seller's qualifications. In addition to checking the "blacklist" before online shopping, consumers can know whether the seller has any disclosed fraud or illegal behavior, and identifying the seller's qualifications is also an important means to ensure the safety of online shopping. Consumers should generally know whether there is a third-party payment or cash on delivery when viewing the website; Regular websites should generally have free customer service calls; In addition, all kinds of certification marks hanging under the seller's website are also the focus of consumers' attention. Generally, the certification marks used by legitimate websites must be approved by relevant institutions, and the certification marks are linked to the corresponding third-party certification pages, and the certification is within the validity period. If the logo at the bottom of the website can't be clicked to view the authentication content or the link content is incorrect, it may be counterfeit, so this kind of website should pay special attention to consumers. Be cautious when buying online games and digital products. According to the analysis, online games and digital products rank in the top two among many consumer complaints, which reflects that the protection of consumer rights and interests in these two fields is more prominent, and consumers should pay special attention to these two types of transactions. Online games are mainly due to the virtual nature of their transactions, and digital products often have a large transaction amount. Problems and disputes mainly appear in product quality. When consumers trade online games and digital products, first, they choose a third party to guarantee payment, and second, they choose an authoritative and formal website to trade. The third party guarantee payment or cash on delivery is selected for intransitive verb transaction payment. Safe and reasonable payment is an important means to ensure the safety of consumers' funds. In many cases where consumers' rights and interests are damaged, unreasonable payment methods are an important reason for consumers' damage. Generally, regular and legal websites will provide consumers with third-party guaranteed payment and cash on delivery payment methods. Accordingly, in the seller's transaction process, consumers are required to pay in advance, which is generally suspected of fraud and illegality. Consumers should choose the payment method carefully and avoid paying directly to each other. Seven, learn and master the basic knowledge of secure online shopping. Many online shopping consumers are deceived mainly because they lack understanding of online shopping, have no basic knowledge of online shopping safety, and can't tell the truth when faced with the low-price temptation and phishing adopted by criminals, thus making behaviors that are unfavorable to them. Therefore, before online shopping, consumers must first consult friends who are familiar with online shopping, read information such as anti-fraud common sense provided by netizens or third-party guarantee institutions, and master basic online shopping safety common sense to avoid being deceived. Article 25 of the Law on the Protection of Consumers' Rights and Interests, if an operator sells goods by means of internet, television, telephone or mail order, consumers have the right to return them within seven days from the date of receipt of the goods, without giving reasons, except for the following goods: (2) Fresh and perishable; (3) Digital commodities such as audio-visual products and computer software downloaded or unpacked by consumers online; (4) newspaper delivery. In addition to the goods listed in the preceding paragraph, other goods that are not suitable for return according to the nature of the goods and confirmed by consumers at the time of purchase are not returned without reason. The goods returned by consumers shall be in good condition. The business operator shall refund the commodity price paid by the consumer within seven days from the date of receiving the return. The return freight is borne by the consumer; Unless otherwise agreed between the operator and the consumer, such agreement shall prevail. Everything has two sides. Online shopping is a double-edged sword. It saves us time and energy, but it may also invade our privacy at any time. Therefore, we must make clear the question "What are the precautions for online shopping". The disadvantages of online shopping cannot disappear. What we can do is to use our usual legal knowledge to ensure the quality of the products we buy and safeguard our rights and interests by screening our shopping platforms and products.
