Charging one shipping charge per order - when an order has items from two different ship. profiles

[JC85]

I have a website (https://www.thebrushandbroom.co.uk/) that has two different shipping charges setup in a profile for the UK. 

These are essentially:

Small items - charge £3.99
Oversize items - charge £9.99

Now, when a customer orders a small item with a large item - we should ONLY charge them one shipping charge... the largest/greatest.

However, this doesn't appear to be the case. We are able to cover the shipping in a single fee because the smaller items can be included within the package for the larger item. So, we are able to purchase on shipping label and combine the goods ordered. But, on the checkout/front-end, customers are being presented with two charges and this makes it off-putting for customers.

Is there any logic or rule that can be put in place to ensure that only one charge - the greatest charge - is applied per order?

Thanks in advance!

Large/oversize products

Standard size products

I achieved this by reaching out to Shopify support and they configured something that wasn't available in the UI.

That was the only way to do it, that was also awhile ago so maybe things have changed, but worth a try if you can't see a setting for it in the UI.

Hi @JC85!

Yes, you can apply only one charge - the greatest charge per order. By default, Shopify adds up rates when items come from different shipping profiles or conditions, which is why customers are seeing combined charges.

A simple, native fix is to move all your products into one shipping profile and use weight-based rates to control the logic. Here’s how:

• Assign low weight (e.g., 0.1 kg) to small items

• Assign higher weight (e.g., 10 kg) to large items

• Set the following rates in the profile:

  • £3.99 for orders up to 5 kg

  • £9.99 for orders over 5 kg

  • Free shipping for orders over £100 (set as a price-based rate)

With this setup, only one shipping rate is applied per order, and the highest one wins when both small and large items are in the cart. Plus, customers spending over £100 get free shipping automatically.

It’s a clean solution that works entirely within Shopify, no apps needed!
