| Themes                     | Renders through the **Elite Embed Core** app embed. Works with any Online Store 2.0 theme; no theme code is edited.                                                                                                                                                                                                                                                                                   |
| Devices                    | Bundle pages work on desktop, tablet and mobile. Preview at mobile width before launch.                                                                                                                                                                                                                                                                                                               |
| Checkout                   | Discounts apply automatically at checkout through a Shopify Function. Works with Shopify checkout and, with the [checkout compatibility setting](/get-started/settings.md#checkout-compatibility), third-party checkouts.                                                                                                                                                                             |
| Cart and orders            | The cart shows one bundle line with the picked items listed under a Show/Hide toggle, and a free gift as its own line at $0; the order carries the real SKUs; inventory is tracked on the real products. Side-cart apps and 3PLs keep working. A bundle bought on a subscription is the exception: its items are separate cart lines, because Shopify does not merge lines that carry a selling plan. |
| Subscription apps          | Any app that sells through Shopify selling plans, such as Recharge, Appstle, Seal, Loop, Skio or Shopify Subscriptions. Every product in a bundle must be in one plan in that app; the bundle connects that plan in **Config → Subscriptions**. Build-your-own and multi-option bundles only. See [Subscriptions](/create-bundles/subscriptions.md).                                                  |
| Inventory                  | Out-of-stock products or variants are shown as sold out and cannot be bought. In a multi-option bundle, if every choice in a required option is unavailable, the whole bundle is unavailable until stock returns or the option is changed.                                                                                                                                                            |
| Metafields in product data | Text, number, date, URL and colour product metafields, and lists of these. Their definition needs **Storefront access** turned on. See [Product data](/customize-and-publish/product-data.md).                                                                                                                                                                                                        |
