To override the handling time for a particular listing(s), you'll need to do the following:

  1. Create a new product group for the listing(s) in question.
    From the left-hand menu select "Products --> Product groups", then click the "Add a product group" button.
    Then enter the details for your new product group, including the details of which product(s) are to be included in this group (i.e. the SKUs for the product(s), or you can also filter products to be included by price, weight, category or brand.)

  2. Create a new shipping policy, assign the new product group to it and select your desired handling time for the product(s).
    From the left-hand menu select "Settings --> eBay Australia --> Shipping", then click the "Add new shipping policy" button.
    Enter a name for your new shipping policy, select your newly created product group and choose your desired handling time for the product(s).
    Finally enter your shipping fee for the policy and then click the "Update" button.

  3. Click the "Synch policies button" to synch your shipping policies with eBay.

  4. Finally, from the dashboard, click the "Upload to eBay Australia" button.
    This will upload a product feed to eBay and assign the desired product(s) to your newly created shipping policy.
