Hi,
To get the shipping information you will also need to activate Selling Manager on eBay. It is free, and it allows MyCostPro to get the shipping expenses when you ship through eBay.
I pulled the instructions here on how to activate Selling Manager.
1. On your my eBay page, click the Account tab.
2. Click Subscriptions in the menu that appears. ...
3. Click the eBay Selling Manager (or Selling Manager Pro) Learn More link.
4. Read the information on the resulting Selling Manager page, and then click the Sign Up Now link.
