This is based on the requirements of different stores.

It is not decided by you. Some stores require you to place an order of more than 200 yuan at a time, that is, all goods can be mixed batches, while some set the minimum order quantity of a single product to 10, then you must reach a certain amount or quantity of 10 to order at wholesale prices. After you add all the goods you like to the order, submit the order, do not pay first, contact customer service about the price or change the postage before paying. The merchant will ship the goods after you pay. Please do not confirm receipt until you have received the goods. Once you receive the goods, if there are quantity or quality problems, promptly feedback to the merchant for negotiation. If you have not received the goods for a long time and the system prompts you to confirm receipt, you must apply for a refund at this time. Once there is a problem that cannot be resolved through negotiation with the merchant, you will contact Alibaba's Xiaoer, that is, the staff to handle it!
