First, ask about the quality of the goods. On the product page, most sellers will exaggerate the description of the product and avoid the defects of the product. At this time, you can ask the seller in detail about the quality and texture of the goods. For example, if you want to buy clothes, you should ask what fabric this dress is made of. If the other person says "blending" and you don't know what "blending" is, then you can inquire about blending knowledge online and ask after you know it.
Secondly, ask the seller about the after-sales business. For example, if you buy something that doesn't match the description or is not what you want, can you return it? It is worth noting that the chat record with the seller must be kept, which can be used as a voucher for future exchange.
Finally, ask about postage, mailing method and payment method. Some sellers are used to writing "the seller bears the freight" in the freight, but you will be asked to pay the postage later, so be sure to ask if you need to pay the postage. When choosing the mailing method, you should tell the seller your detailed address. Of course, it is best not to choose surface mail, because surface mail is the slowest. When paying the seller, it is best to use Alipay, which is beneficial to the buyer.
Summary: Actually, it's not that troublesome. Generally speaking, goods are covered by freight insurance. If you buy it, you can stay if appropriate. If it doesn't fit, you can return it. The freight platform is reimbursed, but you should pay attention to whether the buyer needs freight. Some goods are returned, and the buyer needs you to pay the delivery freight. At this time, you can find the customer service of the platform, and the customer service will intervene to solve the problem.
In fact, communication is also a matter of size. For example, if you have trouble choosing a size, you can tell the merchant your bust, waist circumference, weight and height, and let the merchant give you a suggestion.
