Price of Grouped Product: Set

Modified on Tue, 9 Jul at 4:47 PM

If you want to list a group of Products as a Set on the Channel, you can configure it in Variational Product Settings via M2E Pro.

We have a Grouped Product – a Dining Set with 1 Table, 4 Chairs, and 2 Cloths. 

Thus, the set includes 3 Child (Associated) Products:

  • Dining Table with the Product Price of $240.00.

  • Dining Chair with the Product Price of $70.00.

  • Dining Cloth with the Product Price of $12.00.


Using this Grouped Product as an example, we will figure out how to calculate Item Price displayed on Channels with different Magento Product and Selling Policy settings.

Calculations based on the selected Price Source 

The final price of a Grouped Product listed as a Set depends on one of the selected Price sources in Selling Policy:

  • Product Price

  • Special Price

  • Magento Attribute

Product Price

Product Price of a Grouped Product listed as a Set is calculated as the sum of all the included options’ prices.

In Selling Policy, we have the following settings:


To begin with, we need to calculate the price of each option included in our Product Set. For that, multiply the price set for this option in Magento by its default quantity.

Default quantity is the number of each particular option included in a Product Set:

The first step is to calculate the price for each option of the Product Set taking into account its default quantity and the Product Price values:

To calculate the price for the entire Product Set, we need to sum up the prices of all the included options. The resulting value will be sent to the Channel as a Product Set Price. In our example, the price of the Dining Set is $544.00

Special Price

With the Special Price selected as a source, the price for the Product Set will be taken from the Special Price values of the included options and sent as regular prices to the Channel.

If the Special Price source is selected, but its value is not defined in Magento Product settings or its From/To dates have already expired, Product Price will be used instead.

If you only enter the Special Price value, without specifying From/To dates, and save the Product, Magento will automatically fill in the From date field with the current date:

Therefore, since the To date is not specified, the Special Price will be active on the Channel as soon as the From date comes and further on (until you disable the Special Price or change the From/To dates).

In Selling Policy, we have the following settings:

The options of our Dining Set have the following Special Price values:

  • Dining Chair

  • Dining Table

  • Dining Cloth

The first step is to calculate the price for each option of the Product Set taking into account its default quantity and the Special Price values:

To calculate the price for the entire Product Set, we need to sum up the prices of all the included options. The Product Set is listed on the Channel with a price of $494.90.

Magento Attribute

With the Magento Attribute selected as a price source, the price value for the Product Set will be taken from the selected Attribute of a Parent Product. 

For the Product Set to be listed on the Channel, Magento Attribute must contain a numeric value.

To enable automatic Currency conversion, make sure that the Price value is set to be taken from Magento Attribute with Price Catalog Input Type:

If you choose another Catalog Input Type, the relevant Magento Attribute value will not be automatically converted.

In Selling Policy, we have selected a Magento Attribute with the name of “Channel Price”: 

The Magento Attribute has a value of $499.99 and it is taken from the Parent Grouped Product.

The Product Set Price will be equal to the Magento Attribute value.

The Product Set is listed on the Channel with a price of $499.99.

If you select one of the Magento Attributes as a price source, but its value is not defined in Magento Product settings, the Item will not be listed on the Channel.

Calculations based on Price Change settings

Apart from the selected price source, the final price of a Grouped Product listed as a Set depends on Price Change settings in Selling Policy.

To show you how the Price Change settings affect the results of Product Set Price calculation, in our use cases below we have selected the Product Price source and such options as Absolute Value Increase (case 1) and Percentage Decrease (case 2).

Mind that these are just examples and you are free to select any of the four Price Change options you want and set any preferred value for it:

Besides, instead of the Product Price source, you can choose the Special Price or Magento Attribute source – the price calculation process will stay the same.

Case 1. Product Price + Absolute Value Increase

In the Selling Policy, Price Change is set to Absolute Value Increase:

Calculating Product Set Price: Product Price + Absolute Value Increase = $544.00 + 7 = $551.00

The Product Set will be listed on the Channel with a price of $551.00.

For a more detailed explanation of how the Product Set Price is calculated, check out the Product Price section of this article.

Case 2. Product Price + Percentage Decrease

In Selling Policy, Price Change is set to Percentage Decrease:


Calculating Product Set Price: Product Price - Percentage Decrease = $544.00 - 40.5% = $323.68

The Product Set will be listed on the Channel with a price of $323.68.

VAT Rate Included

In Selling Policy, it is possible to indicate the VAT Rate – percent value that will be added to the final price of your Product.

The VAT rate sent by M2E Pro is perceived as a proper VAT rate only by eBay. Click here to learn more.

Amazon and Walmart consider the VAT rate sent by M2E Pro in a different way – as an additional price increase.

Let’s see how the Product Set price will be calculated if we add the VAT Rate value and configure particular Price Change settings.

Case 1. Product Price + VAT Rate + Absolute Value Increase

In Selling Policy, Product Price is selected as a source. Price Change is set to Absolute Value Increase. VAT Rate is set to 19%. The Add VAT% on top of Price option is enabled.

Using the Add VAT% on top of Price option in eBay Selling Policy, you can either:

- add the VAT rate on top of the Item Price (choose “Yes”);  

- include the VAT rate in the Item Price (choose “No”).

The first step is to calculate the Product Set Price taking into account two factors:

  • price value for the entire Product Set (see the Product Price section of the article)

  • Price Change settings

Product Price + Absolute Value Increase = $544.00 + 3 = $547.00

Instead of the Product Price source, you are free to choose the Special Price or Magento Attribute source – the price calculation process will stay the same.

Then we need to calculate the VAT Rate value for our Product Set:

Product Set Price with Price Change settings applied x VAT Rate (%) = $547 x 19% = $103.93

The final Product Set Price will be calculated according to the following formula:

(Product Price + Price Change) + VAT Rate value = ($544.00 + 3) + $103.93 = $650.93

The Product Set is listed on the Channel with a price of $650.93.

Case 2. Product Price + VAT Rate + Percentage Increase

In Selling Policy, Product Price is selected as a source. Price Change is set to Percentage Increase. VAT Rate is set to 19%. The Add VAT% on top of Price option is enabled.

The first step is to calculate the Product Set Price taking into account two factors:

  • price value for the entire Product Set (see the Product Price section of the article)

  • Price Change settings

Product Price + Absolute Value Increase = $544.00 + 6% = $576.64

Then we need to calculate the VAT Rate value for our Product Set:

Product Set Price with Price Change settings applied x VAT Rate (%) = $576.64 x 19% = $109.56

The final Product Set Price will be calculated according to the following formula:

(Product Price + Price Change) + VAT Rate value = ($544.00 + 6%) + $109.56 = $686.20

The Product Set is listed on the Channel with a price of $686.20.
