Do friends in Yiwu know the wholesale price of 8 pairs of socks 10 yuan?
There are 0.75-0.85. There are better ones, but the profit is small. If there is a defective product above 70 cents, you can exchange it. If it is less, it is not worth replacing it (the freight is not enough). Generally, it is the first time to get the goods by yourself, and then logistics delivery will do. If you are flexible, you can also collect money. If you still don't understand, send a QQ number and I'll add you.
