Suning.cn, how come the store mentions itself?

when you place an order, you can choose the delivery method, you can choose the store to pick it up, you choose the nearest Suning store, and they will call you when the goods arrive, so you can pick up the goods. It seems that the store can't use cash on delivery. I think it's better to use a mobile credit card and send it to your home, so you don't have to pick up the goods yourself.
