Hello! There are two ways to bill: 1, and bill by yourself according to the purchase amount (mainly using JD.COM coupons); 2.JD.COM Mall will bill itself (because the items are not in the same warehouse, it will choose to bill). In the past, a lot of bills were issued in JD.COM, but now it is much less than before. Basically, the goods are transferred from other warehouses to this warehouse, and then packaged and delivered together.
