Price of Grouped Product: Variations

Modified on Tue, 30 May, 2023 at 10:38 AM

If you want to list a Grouped Product as a Multi-Variational one on the Channel, you can configure it in Variational Product Settings via M2E Pro.

We have a Grouped Product, a fitness equipment kit, that includes 3 Child (Associated) Products. 

Each Child Product has the following Product Price values in Magento:

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.

For eBay: If you are listing a Grouped Product as a Multi-Variational one, and the Ignore Variations option is enabled in Selling Policy, a Grouped Product will be listed as a Simple one, without variations. In this case, the price of the cheapest Child Product will be submitted to eBay.

As our Grouped Product is listed as a Multi-Variational one, the channel’s item price will range depending on the selected variation. That is why the prices of Grouped Child Products are taken as a basis for final item price calculation.

Calculations based on the selected Price Source 

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

  • Product Price

  • Special Price

  • Magento Attribute

Product Price

With the Product Price selected as a source, the prices for Grouped Product’s variations will be taken from the default Magento Price attribute values.

In Selling Policy, we have the following settings:

The variations of our Grouped Product will be submitted to the Channel with the following prices:

  • Yoga Mat – $18.99

  • Stability Ball – $24.75

  • Magic Ring – $9.17

Special Price

With the Special Price selected as a source, the prices for Grouped Product’s variations will be taken from the corresponding Special Price values 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 variations of our Grouped Product have the following Special Price values:

  • Yoga Mat

  • Stability Ball

  • Magic Ring

Thus, the variations of our Grouped Product will be submitted to the Channel with the following prices:

  • Yoga Mat – $10.99

  • Stability Ball – $20.75

  • Magic Ring – $6.17

Magento Attribute

With the Magento Attribute selected as a price source, the price values for the Grouped Product’s variations will be taken from the Attributes assigned to them. 

For the Item 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” and the following values for our Grouped Product’s variations:

  • Yoga Mat

  • Stability Ball

  • Magic Ring

The variations of our Grouped Product will be equal to the corresponding Magento Attribute values of Child Products and submitted to the Channel with the following prices:

  • Yoga Mat – $15.50

  • Stability Ball – $24.00

  • Magic Ring – $12.95

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 Multi-Variational one depends on Price Change settings in Selling Policy.

To show you how the Price Change settings affect the results of Item 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 Selling Policy, Price Change is set to Absolute Value Increase:

We need to calculate the Channel’s price for each variation of our Grouped Product individually based on the Price Change settings. 

The calculation formula is the following: Product Price value + Absolute Value Increase.

Yoga Mat: $18.99 + 7 = $25.99

Stability Ball: $24.75 + 7 = $31.75

Magic Ring: $9.17 + 7 = $16.17

Case 2. Product Price + Percentage Decrease

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


We need to calculate the Channel’s price for each variation of our Grouped Product individually. 

The calculation formula is the following: Product Price value - Percentage Decrease.

Yoga Mat: $18.99 - 40.5% = $11.30

Stability Ball: $24.75 - 40.5% = $14.73

Magic Ring: $9.17 - 40.5% = $5.46

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 Item 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 price for each Grouped Product’s variation taking into account two factors:

  • The Product Price value of each Grouped Product’s variation

  • Price Change settings

Yoga Mat: Variation’s Product Price + Absolute Value Increase = $18.99 + 3 = $21.99

Stability Ball: $24.75 + 3 = $27.75

Magic Ring: $9.17 + 3 = $12.17

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 amount value for each Grouped Product’s variation:

Yoga Mat: Variation’s Product Price with Price Change settings applied x VAT Rate (%) =  $21.99 x 19% = 4.18

Stability Ball: $27.75 x 19% = 5.27

Magic Ring: $12.17 x 19% = 2.31

The final price for each Grouped Product’s variation will be calculated according to the following formula:

(Product Price + Price Change) + VAT Rate value

Yoga Mat: ($18.99 + 3) + 4.18 = $26.17

Stability Ball: ($24.75 + 3) + 5.27 = $33.02

Magic Ring: ($9.17 + 3) + 2.31 = $14.48

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 price for each Grouped Product’s variation taking into account two factors:

  • The Product Price value of each Grouped Product’s variation

  • Price Change settings

Yoga Mat: Variation’s Product Price + Percentage Increase = $18.99 + 6% = $20.13

Stability Ball: $24.75 + 6% = $26.24

Magic Ring: $9.17 + 6% = $9.72

Then we need to calculate the VAT Rate amount value for each Grouped Product’s variation:

Yoga Mat: Variation’s Product Price with Price Change settings applied x VAT Rate (%) =  $20.13 x 19% = 3.83

Stability Ball: $26.24 x 19% = 4.99

Magic Ring: $9.72 x 19% = 1.85

The final price for each Grouped Product’s variation will be calculated according to the following formula:

(Product Price + Price Change) + VAT Rate value

Yoga Mat: ($18.99 + 6%) + 3.83 = $23.96

Stability Ball: ($24.75 + 6%) + 4.99 = $31.23

Magic Ring: ($9.17 + 6%) + 1.85 = $11.57
