What this guide covers
Define what can join a bundle, then separately tell the storefront where the campaign is intended to appear.
Include broadly or precisely
Select products, specific variants, or whole collections. Collections resolve to products when you publish, and an optional quantity cap can count per product or per variant.
Carve out exceptions
Excluded products and variants stay ineligible even if an included collection would otherwise bring them in.
Keep placement separate
Product, collection, landing, and cart are placement hints. They do not create additional campaign types.
