1. Create a new product group for similar/same sized products that ship in their own box. 
  2. Add a carrier rate to the product group
  3. Within the package settings of the carrier rate for that group, edit the default package, and change the 'Number of items' to 1, and enter in the dimensions of the box it ships in. The package settings will look something like this: 

When someone orders 3 products from this group, we will get a shipping rate for three separate packages of 18x18x18, and add up the rates.

Let's dive a little deeper into a full set-up with product groups for differently sized products. 


In this example we have 3 groups: 

  • Default
  • Watermelons
  • Crate of Apples

Let's take a look at the Default group's rates first:

Scroll to the Package Settings section of the rate:

This is the default package setting, which says basically, take all products and put them in a box sized 5x5x5, and return a rate. So whether there is 1 or 10 or 50 products, the rate will be as if all products ship together in a box. 

Now let's take a look at the Watermelon group's rates:

Scroll to the Package Settings section of the rate:

This package setting, which says "Up to 1 item", means that for each item from this group, it will get a rate for it in its own package of 18x18x18. 

So if there are 2 watermelons in an order, the rate will be for two separate packages of 18x18x18. 

Now let's take a look at the Crate of Apples group's rates:

Scroll to the Package Settings of the rate. 

This package setting, which says "Up to 1 item", means that for each item from this group, it will get a rate for it in its own package of 26x12x6. 

So if there are 2 crates of apples in an order, the rate will be for two separate packages of 26x12x6. 

The app will add up all the rates together. 

So, when there are multiple product groups in an order, the app will show a blended rate

The blended rate by Default will add together each product group's rate up together and offer it as a single rate. 

So if someone orders: 

  • 5 products from the Default group
  • 10 Watermelons
  • 2 Crates of Apples

The app will get a rate for....

  • The 5 products from the default group in its own box 5x5x5
  • A rate for 10 watermelons, each shipping its own box 18x18x18
  • A rate for 2 Crates of Apples, each shipping its own box 26x12x6
  • All these rate will be added together. 

You can add a rule to the blended rate if you don't want to charge for the Default products when a large product is in an order. 

Often, when there is a really large product in an order, the smaller items from the Default group can be added to the shipment at a negligible ship cost, and so you don't want the ship cost of the Default products to be added to the ship cost of the larger items. 

Here is how you can add a rule to the blended rate to do that. 

Click the Blended Rates tab

Click "Configure" or "Edit" on your blended rate. 

 Scroll to the Rules section, and click 'Add Rule'

Choose the third option: Free Shipping When Product Group is Present, and click Next

Configure the rule like this: 

This is what it looks like saved:

Add another rule for the Watermelon:
