The main problem I am having is understanding how to add shipping costs for various items in my cart. All have a different weight, some heavier than others by a lot. In Australia we are charged by 500 gram increments, and as most items are going overseas the cost per half kilo is around $20. The next half kilo increases about $20 and so on.
What I don't understand is how to tie the weight of a product to the shipping cost, and how to implement it to add up to a final amount for shipping
Is there some help available to explain this?
Some say it can't be done, while others are doing it.
