Shipping Cost per item

Hello,

How can we set the shipping cost to be something like:

1 item: 4$
2 item and more: 4$ + 2$ each additional items?


1 items = 4$ shipping
2 items = 6$ shipping
3 items = 8$ shipping
4 items = 10$ shipping
...

Thanks,
Have a great day!

Hello Nicolas,

Thank you for your fast answer.

I would like to confirm my understanding.

Is that means that I have to create manually 10 shipping in case a customer buy between 1 to 10 items?

Also, is it mean that I have to create 10 shipping items manually for each "zone", like:

Zone1: Same State, the shipping is 4$ for the first item then 2$ for each additional item;
Zone2: Same Country, the shipping is 6$ for the first item then 3$ for each additional item;
Zone3: International, the shipping is 8$ for the first item then 4$ for each additional item;

That means 30 shipping items?

Thanks,
Have a great day!
Sébastien
