1, check the registration time of the brand you are sure to buy.

2, not to say that the higher the level of the seller, the better, but to look at his credibility. The most important thing is to look at his seller's credibility. If it is lower than 97%, don't look at it. Such a seller is very dangerous, no matter how high his advertising and level are.

3. When you choose several at the same time and hesitate, you'd better choose a "consumer protection plan, which has been paid at present"

Then when you make a preliminary decision, you must go to his shop to see if what he sells is mainly bought by you. On Taobao, there are many things sold in the times.

There is another good method that I have been using. If you are still hesitating, ask the customer who bought the same item with you, ask a few more questions, and it is easy to get the result you want after summing up.

The above is my own shopping experience, I hope it will be useful to you!
