I am am trying to list an item to sell from Canada. I have selected charge actual cost, so that it is calculated then a potential buyer looks at my listing. but it won't let me post unless I add an actual shipping cost, which I obviously don't know as I dont know the location of the buyer. Any help would be appreciated.

why am I being asked to input shipping cost when I have selected, charge actual cost? | Selling
