Thank you for your reply. I read the instructions and followed them carefully.
I bought the Table Rate plugin which is supported by your plugin ad configured it.
Unfortunately I still have no shipping costs in my feed:
<g:item_group_id>21309</g:item_group_id>
<g:shipping/>
<g:shipping_label>packet</g:shipping_label>
Can you please advice what to check next ?
Thank you in advance
