I'm using the table rates (weight) to calculate the shipping costs. There are some products that have fixed shipping costs.
For example. I've a total of 7 products in my cart. 5 of these products are covered by the shipping rates. These 5 products have a total weight of 20kg. The costs of 20kg is €20.
The other 2 products have a shipping costs of €10 a piece. The weight of these 2 products must not be include into the table rates.
So the total costs of shipping is:
€20 for the first 5 products and 2 times €10 for the last 2 products
So the total shipping costs has to be €40
Does anyone know an extension/ a way to fix this problem?
