WooCommerce cart guide
How to add multiple WooCommerce products to the cart with one button
Create one fixed bundle with the products, exact variations, and quantities every customer must receive. One Add to cart action adds the bundle container and every required component. Free keeps every component required: customers cannot remove one, change its quantity, or choose an alternative.

Use a fixed bundle when every item is required
The key question is who chooses the contents. Advanced Bundles Free works when the store owner defines the complete set before the customer reaches the product page.
| Question | Fixed bundle | Customer-selected products |
|---|---|---|
| Who chooses the products? | The store owner chooses every required simple product or exact variation. | The shopper chooses products from a grouped product, order form, or configurable product. |
| Who chooses the quantities? | The store owner sets one positive whole-number quantity for each component. | The shopper can change quantities or leave products out. |
| What does the cart action add? | The bundle container and all required component lines are added together. | Only the products and quantities selected by the shopper are added. |
| Best fit | Starter kits, repair kits, gift sets, and product packs with fixed contents. | Product lists, build-your-own kits, mix-and-match boxes, and optional add-ons. |
One button does not hide the component lines
The customer buys one coherent bundle, but WooCommerce still receives the component detail needed for pricing, stock, tax, shipping, orders, and refunds.
A zero-value bundle container groups the purchase. Required components carry their own financial and fulfilment data, so the bundle is not charged twice.
Current component prices
The total is each component current price multiplied by its fixed quantity.
Combined stock checks
WooCommerce checks all required quantities in the cart and revalidates them before checkout.
Stable order detail
Purchased component names, SKUs, quantities, totals, tax, currency, and bundle structure remain in the order snapshot.

Multiple-product cart questions
Answers describe the fixed workflow in Advanced Bundles Free.
Does one button create one cart line?
No. One action adds a zero-value bundle container and the required component lines. Components keep the detail WooCommerce needs for prices, stock, tax, shipping, orders, and refunds.
Can the button add a specific product variation?
Yes. The store owner can configure one exact existing variation and a fixed quantity. Customers cannot switch its attributes or choose another variation in Free.
Can customers remove one product after adding the bundle?
No. Free treats every configured component as required. Use a grouped or configurable product when shoppers need to choose the contents.
Can I set one discounted price for the whole bundle?
No. Free totals the current component prices. Bundle-specific discounts and a separate fixed-price strategy are not included.
What happens when one component is out of stock?
The bundle cannot be purchased when a required quantity is unavailable and WooCommerce backorders are not allowed. Stock is checked again before checkout.
