After the buyer places an order, the merchant indicates on the order that the goods will be delivered within 45 days, because the merchant is worried that the inventory is not enough and needs to be transferred or re-produced. Therefore, the delivery within 45 days is the longest delivery time for a merchant to predict his goods, but it doesn't have to be about 45 days. If the merchant has stock, the product will be delivered within 72 hours. If the goods need to be transshipped, they can be delivered in about seven days. If the product needs to be reproduced, it usually takes about 20 to 30 days.
