As a seller I offer free shipping how do I know what the shipping cost will be on an offer?

I am an eBay seller and I’ll except offers and always have free shipping. how can I

find out what the cost will be when someone makes an offer for the shipping before I accept the offer?

It's been a LONG time since I received an Offer, but I believe you can click on the buyer's feedback number and see where they are located.
