I have Table Rates set up correctly and good to go however, i'd like to add a 'signed for' option to the shipping. Is that possible?
So, for example, on checkout, the customer can choose to have standard shipping or choose to have their parcel 'signed for' which would add an amount to the shipping.
Anyway, help would be great, im pretty new to Magento.
Yes possible; you can provide options of shipping methods to your customers and customers can choose suitable shipping method. However you need to develop "Signed for" shipping method.
Hope it helps yo
Now that's the part I would have no idea about.
Is it possible just to duplicate the Table Rates and adapt that?
