Do you sign or inspect the goods first when you receive the express delivery?
Some express delivery is to give you something directly, sign for it first, and they don't care. There is also a good courier to remind you to see what you bought in person after signing. In fact, the signature is not so important in the order in which you look at things. Signing just means that you have received them. If you feel bad and dissatisfied after going back to see something, you can contact the seller to return it. It is also possible. If the seller disagrees, he can be sued on Taobao. In this way, his shop may not be guaranteed, and he will think about it. So it is generally safe to sign!
