Updating a listing where the original quantity was 1 and I now have another 4 to add.
Changed quantity to 5. Original shipping options were UK 1st class and 2nd class and overseas for Europe and the Rest of the World.
There are only options for "Each Extra Item Will Add" X "To Shipping Cost" for 1st class and my first overseas shipping. I am unable to offer a discount on 2nd class or the Rest Of The World.
As the Rest Of The World additional shipping will be £5 I am not willing to take the risk of editing the listing.
