I have 20 identical items I wish to sell at a fixed price (Buy Now).
I will ship up to 5 for the the same shipping fee: i.e. postage on one is £3; total postage on 2 is £3; total postage on 5 is £3.
If I set:
"Each extra item will add £0 to shipping cost"
this would appear to allow to all 20 to be shipped for £3!
Is there any way round this - help, please!
