Hi
The 'price per product' is a very good plugin idea
Where the problem comes in is... I already charge a set 'one off' generic shipping fee on a range of over 500 products, a purchaser is charged the same amount if they buy 1 or 10 different products...
The 'one off' generic shipping fee is set in the 'price box' of a manual 'shipping method'...
I am now adding a completely different category of products, for some I want free delivery for others I want to charge...
If I set "price per product" in a new added item, the 'one off' generic shipping fee I already charge is also added...
