# I have lost my SKUs !

**Wide Hello to you!** 😁

|| 💡 This article is only useful for bundles created with the variants' system, not for automatic discounts. [Learn more about the difference](https://help.widebundle.com/en/article/differences-between-automatic-discounts-and-variant-bundles-ootmn6/) ****

You have configured offers on WideBundle using the variant system and your variants have been replaced, therefore, you have lost your SKUs

This is completely normal!

### How WideBundle variant system works

To understand the problem you first have to understand how this system works

For these bundles, we decided to use the Shopify variants ( [What is a variant on Shopify?](https://help.shopify.com/en/manual/products/variants))

The offer on WideBundle becomes an option of the product just like the color or the size of a product.

So if you sell a product available in 2 colors (White and Black) then your product will have 2 options: An "Offer" option and a "Color" option.

If you want to create an offer "2 products bought = 1 product offered" for this product, WideBundle will create all the corresponding variants.

Here are the variants that will be created:

**Variant #1** : *(in case the customer takes 3 black products)*
**Offer** : 2 products bought = 1 offered - **Color** : Black, Black, Black

**Variant #2** : (in case the customer takes 3 white products)_
**Offer** : 2 products bought = 1 offered - **Colors** : White, White, White

**Variant #3** : (in case the customer takes 2 white products and 1 black product)_
**Offer** : 2 products bought = 1 offered - **Colors** : White, White, Black

**Variant #4** : (in case the customer takes 2 black products and 1 white product)_
**Offer** : 2 products bought = 1 offered - **Colors** : Black, Black, White

As you can see, 4 variants have been created corresponding to all the combinations of 3 products that a customer can buy.

### How to do with my SKUs ?

Since WideBundle removes variants and replaces them, you will have to create new SKUs dedicated to the offers
