If a buyer purchases more products from you within one hour of their first purchase, they are automatically combined into a single shipment to keep shipping costs down.
As a seller, keep the following in mind for combined shipping:
The same shipping label will appear on each individual product card in the app.
You receive one email per product sold, but all emails contain the exact same label.
Use only one label. Pack all combined products together in one parcel and show the shared shipping label at the DHL service point.
