Cause

eBay returns this error if your listings miss a valid postage service.

Solution

Please update the Shipping policy or edit it:

  1. Open your Policy manager (eBay Business Policies direct link and click on “opt in”)
  2. Look for the policy you’ve picked on Nembol and update it by clicking on edit, and then on save (in this way you will update the postage info)
  3. Once done, make sure to select this same policy in your “List to eBay” settings on Nembol – See the screenshot below.
  4. Remember to save.

If that doesn’t work, please consider editing or creating an additional Shipping policy (even similar) to associate with Nembol.
