First: read his purchase instructions carefully. There may be other conditions in it, such as the packaging of the return, whether to use it, freight and so on. If you approve of them, buy them again.

Second: some 7-day returns are really added and displayed in the place specified by the store. No one else did. He just advertised that he could return the goods in 7 days, and made an icon similar to Taobao and put it in the description of the store. You have to distinguish carefully. Doesn't mean the latter won't be refunded. Relatively speaking, the guarantee is not official.

Third: Be sure to use Alipay. You agree to pay when you are satisfied.

Fourth, we should be psychologically prepared for problems such as defective goods or poor colors and pictures, and don't be too harsh when buying things on Taobao. Otherwise, it is easy to get angry.

Above, there should be no problem.
