cumulative ship price based on weight

I have a product that i want to charge 6$ to ship. if they buy 2 its 12$ and so on. each item is 1.3 kg.

Why when i set up weight based shipping and order 4 the shipping is 6$ and not 24$

So frustrating

Hey @fineedge

Is the product’s weight entered correctly? I am assuming you built the weight-based shipping within Shopify to have it chunked out:

0-1.3lbs = $6

1.3lbs -2.6lbs = $12

so on and so forth?

Let me know if you have any questions, or have any more insight to your product.

Thank you,
