For shoppers
What are bundles?
Products on this store may be part of a bundle: a group of items sold together, usually at a lower combined price. The offer appears on a product page, and one button adds everything to your cart.
There are five types:
#Fixed set
A fixed set of products the store has chosen. You don't pick the items, though you may be able to choose options like size or colour for each one (see Choosing a size or colour).
The widget shows each product in the set, the individual prices, the total you'd pay compared to buying separately, and the saving. Click the add-to-cart button and all items are added at once.
#Buy X Get Y
You buy a set number of "trigger" products and receive a set number of other products free or at a reduced price. For example: buy two candles and get a candle holder at 30% off, or buy three skincare items and get a travel bag free.
The widget has two sections: the items you buy and the items you receive. It shows the price for each side. The saving or "FREE" label appears on the reward items.
#Buy One Get One (BOGO)
Buy One Get One gives you a second item free or at a discount when you buy the first. The two items may be the same ("buy a T-shirt, get a second T-shirt free") or different ("buy a backpack, get a water bottle 50% off").
The widget shows the item you pay for and the item you get at a reduced price. Both are added to your cart when you click the button.
#Volume discount
The more you buy, the bigger the discount. The widget shows tiers like "Buy 3+ units, save 10%" or "Buy 10+ units, save 25%." Pick the quantity you want and the widget shows your price per unit, the total, and your saving. A nudge bar shows how many more you need for the next tier.
The discount applies at checkout once you add the quantity.
#Build your own / Mix & Match
You pick items from one or more groups. Each group has a minimum number of items you need to choose, for example "pick at least 3 from Moisturisers" and "pick at least 2 from Serums." A progress indicator in the widget tracks how many more you need before the bundle is complete.
Once you've met all the group requirements, the button becomes active. Click it to add all your chosen items at once.
Some groups may also have a maximum. If you hit the cap, the widget tells you.
#Choosing a size or colour
For many bundle types, you can choose a product option (size, colour, style) directly inside the widget. A dropdown or buttons appear next to the product name. Choosing a different option updates the price for that slot.
#Sold-out items
If any item in a bundle is out of stock, the add-to-cart button shows "Out of Stock" and cannot be clicked. You cannot add the bundle until all items are available again. Contact the store to ask about restocking.
#Bundles sold as a single product
Some stores sell a bundle as a single product with its own page and price. The page shows a "What's included" list. At checkout, Shopify lists the individual components under a "Part of: [bundle name]" label.
