This menu covers Oberlo Chrome extension behavior when placing orders in AliExpress:
Default shipping method – This setting indicates that the Chrome extension is to always choose the selected shipping method if it is available on AliExpress when placing orders. If it is not available, the Chrome extension will choose the cheapest option.
Override phone number – The Chrome extension automatically fills out the customer’s shipping information in AliExpress. You can prevent it from using your customer’s phone number by overriding it with a pre-defined number.
Since you are dropshipping, you don’t want AliExpress suppliers contacting your customers regarding any questions related to their orders.
Custom note – A note will be sent along with your order to the supplier. Use this note to inform the supplier that you are dropshipping and don’t want him to include any invoices or promotional material to product packaging.
Also, this from this menu you can assign a credit card to your Oberlo account for in-app payments for orders.
Note: Credit card details added in this menu can only be used for purchasing products imported from our in-app Supply system. It won't allow you to automatically use this card for placing orders in AliExpress!
