Hello Marc,
Product 1 20€ 3,50€ Shipping
Product 2 30€ 3,50€ Shipping
Product 3 30€ 14,90€ Express Shipping
80€ + 21,90€ = TOTAL 101,90€
The solution will be to :
- Use the "Use price per product" option of your 2 shipping methods configuration page
- Go to your products configuration page
- Block or set a shipping price regarding the shipping method through the "Shipping prices" tab of your product configuration page
For example, if you want a product to be only shipped by the "Express shipping" you'll have to :
- Block the "Standard shipping method"
- Set a price (14,90€) for the "Express shipping"
