In short
Product bundle is a free Shopify section that offers two or three products you pick as a set to buy together, each with its image, price and variant menu, a running total and one Add all to cart button. Shoppers can leave a product out with its checkbox; the button adds the chosen variants in one request to Shopify's Cart AJAX API. The section shows normal prices: any bundle discount is an automatic discount you set up in Shopify. It works in Online Store 2.0 themes without an app.

How to add it to your theme
- Copy the section file into your theme’s sections folder, and any snippet it lists into snippets.
- In the theme editor, choose Add section and pick the one that starts with “Lib ·”.
- Replace the sample text with your store’s own, and set the colors to match your brand.
Questions
- Does the section give a bundle discount?
- No. It adds the products at their normal prices. To discount the set, create an automatic discount in Shopify (Discounts), for example a percentage off when these products are in the cart, and describe it in the section's discount note. The note is only text.
- How are the products added to the cart?
- With JavaScript, one request to /cart/add.js with every chosen variant and quantity; then the shopper goes to the cart or stays on the page with a message, as you choose. A cart:refresh event lets themes that listen for it update their cart count. Without JavaScript the form posts every available product to /cart/add.
- What happens with sold-out products?
- A sold-out product is shown greyed with a Sold out label and never added. Sold-out variants stay in the menu but cannot be chosen.
- Can the shopper change variants and quantities?
- Each product with options has a variant menu, and the price and total follow the chosen variant. The quantity per product is set by you in the block (for example two cups); shoppers include or leave out products with the checkboxes.
- Is the total in the store's currency format?
- Yes. It is formatted from a price rendered with Shopify's money filter, so the currency sign, separators and decimals match the rest of the store.
