Every time a customer adds a new 'Legacy - Single SKU' bundle configuration to their cart (a unique combination of bundle products), Bundle Builder automatically generates a variant of the dummy product. After 100 variants have been generated, Bundle Builder will duplicate the respective dummy product to hold more variants. This process repeats as many times as required.

There can be potentially unlimited numbers of bundle configurations. This means the amount of variants can quickly build up on a bundle's dummy product page.

On Shopify's platform, a regular product page can only hold a maximum of 100 variants. The dummy product page works in exactly the same way.

When you have reached the maximum number of 100 different variants (configurations) of the same bundle, the next time a customer adds a new configuration to their cart, Bundle Builder will duplicate the dummy product and add the variant there. This is how Bundle Builder works around Shopify's limitations.

As long as you continue to sell a bundle, its respective dummy products need to remain in your Shopify admin, even if they are old. Older dummy products are assigned the tag bundle-builder-dummy-legacy.

Newer dummy products will continue to auto-generate variants as normal. The latest version of a dummy product is assigned the tag bundle-builder-dummy-latest.

This cycle will continue every time an additional 100 configurations are added as variants. If the new dummy product auto-generates 100 variants, it will then also duplicate and become an old dummy product.

Example:

Dummy Product A auto-generates 100 variants. It has reached capacity and can no longer generate any more variants. The dummy product duplicates and it becomes an old dummy product.

Dummy Product B is the new dummy product and the duplicate of Dummy Product A. It auto-generates variants with each new bundle configuration until it eventually also reaches capacity at 100 variants. After 100 variants, it also duplicates and becomes another old dummy product.

Dummy Product C then becomes the new dummy product, while Dummy Product A and Dummy Product B remain in place as old dummy products.

No, you don't have to do anything with duplicate dummy products. Duplicate dummy products are required for Bundle Builder to function correctly. They should not be archived or deleted if you want to continue selling your bundles.

Doing so can cause irreparable issues for your bundles and also remove valuable order data which might be needed for customer returns, exchanges, etc.

However, if duplicate products are becoming a problem for your store, then you do have options that can be taken in different scenarios:

The best way to avoid dummy products is to create native or multiple SKU bundles. This would involve essentially creating the same bundle from scratch but choosing either a native or multiple SKU as the bundle type. You would then need to archive all the dummy products associated with your original single SKU bundle.

However, Multiple SKU bundles aren't suitable for every bundle. For example, if you allow customers to enter Shopify discount codes against bundles then you must use a native or single SKU bundle.

If you wish to stop selling a certain bundle indefinitely, you can set the bundle's status to Draft. This will allow you to continue selling the bundle at a later date without recreating it from new. You can then safely archive any active dummy products associated with the bundle.

When you start selling your bundle again, you can reactivate your dummy products and continue using them as normal. In this scenario, your dummy products will remain on the system.

You can delete a bundle from your Bundles page if you are going to permanently stop selling it. However, this won't remove its dummy products. You must manually archive dummy products to remove them from your active Products.
