Fed up of international shipping

I keep getting caught out with the postage costs for international postage, so I have decided to stop selling abroad. I have over 400 listings - is there a way to remove the international shipping costs from them all? I’ve looked at the ‘bulk edit’ tab, but there isn’t an option for this (only Europe), and if I select bulk edit postage, it asks me to do the same postage for every listing, which doesn’t work as everything is different sizes/weights. Any ideas?

Go to bulk edit, select the all at the top of the listings, a message comes up about postage, alter the postage you do have to change the uk postage as well. Hence why I have a fixed rate Uk postage. If you have different postage amounts per item it then has to be done manually.

One thing if you have several with the same rate of postage you can tick those and amend in bulk.

I have used fixed rate for ages including US dies not stop sales as people appreciate postage is not cheap.
