Bundles
Bundles
Sell packs with one buy button — expanded into real products at checkout.
View as MarkdownPacks sell more units per order — but only if buying one is a single click and the price never surprises anyone. Bundles gives you both: a pack is a real product with one buy button, the price you set is the price checkout charges, and when the order lands your inventory, fulfillment, and reports see the real items, not a mystery SKU.

"SheaX 2-Pack" — $36 ──checkout──▶ 2 × SheaX Bar ($18 each)
(what the shopper buys) (what your store fulfills)- The pack is a product. It has its own page, price, and buy button.
- Checkout expands it. A Shopify Function (running inside checkout, on Shopify's servers) swaps the pack for its components at the configured per-item prices. The price you set is the price charged — there is no client-side math to drift.
- Inventory stays true. Pack products carry no stock of their own; selling a 2-pack decrements the component's inventory by 2. One stock pool covers singles and every pack size.
Two kinds of packs

| Storefront | The pack product's own page, or a size ladder on the base product's page | A "build your pack" picker rendered by the Cartrella theme block |
| Set up in | Creating packs | Mix & match |
