Right, so for a heavyweight product such as a hoodie, I implemented an attribute named "heavyweight package" which automatically adds an additional shipping charge. And it works great!
But I was also planning to ship for free all orders over 70 Euros. This is where the problem lays - my added shipping charge for heavyweight products is now added and included in the the product's price (when you checkout) and gives false information on the actual value of the order. And there's also no way to take away that added shipping charge when the order is over 70 Euros.
I must have started doing this arse first. I'm running out of brain cells at this point... Any ideas how to do this properly?
