Let shoppers pick a size and color for each item in a bundle

A shopper buying three T-shirts on a Buy 3 deal often wants three different sizes. Many quantity break widgets add three of the same variant. Here is how per-item pickers work and how to set them up.

A Buy 2 quantity break with a size and color picker for item 1 and item 2, the color list of item 2 open with six swatches — Buy 2 on our demo store: each candle has its own size and color.

The price follows each pick

When sizes cost different amounts, the tier price changes as the shopper picks. On our demo store, Buy 2 of the Fig & Cedar candle in two 8 oz sizes shows $43.20; switching the second candle to 16 oz shows $57.60, and the cart charges $57.60. The add to cart button and sticky bar show the same price.

Picker styles

Dropdowns, buttons or color swatches. Happy Bundle reads the color swatches you set on your products in Shopify.
Sold-out sizes are listed and cannot be picked, or you can hide them.
You can limit an offer to some variants, for example only the 8 oz size.

Set it up

Choose products that have size or color options.
In the offer's design, choose how pickers look; the live preview shows them on your product.

And without an app?

Shopify's own Shopify Bundles app also lets customers choose options like size or color for products in a fixed bundle, up to 3 options and 100 variants per bundle. It has no quantity tiers or mix and match. See Shopify Bundles compared.

Questions merchants ask

Which Shopify quantity breaks app lets customers pick a different size or color for each item?

Happy Bundle does. Each item in a tier has its own size and color picker and the price follows each pick. Bundlex also describes a variant picker per item on its listing.

What happens if a size is sold out?

It shows as sold out and cannot be picked. You can choose to hide sold-out sizes instead.

Does the discount apply if shoppers mix sizes?

Yes. The tier counts every item, whatever size or color it is.
