Can I sell several products together as one bundle?

Yes, with the Product Bundles plugin. Once it is active, Bundle appears as a product type.

1. Go to Products → Manage Products and click + Add Product, then choose Bundle.
2. In Bundle contents, search for the products to include and set a quantity for each.
3. Under Bundle price, pick one:

• Sum of items: the children's prices added up, with an optional Bundle discount %.
• Fixed price: one Bundle price for the whole set.

1. Save.

A bundle has no stock of its own. When one is ordered, each product inside it loses stock (bundle quantity × item quantity). If any product inside is out of stock, the bundle shows as out of stock.
