Attravo Bundles is built to sit inside your existing store. Here's what to know about the other parts of it.

## Themes

The app adds its offers through app blocks and an app embed in the theme editor, so it works with Online Store 2.0 themes without editing code. Older themes that don't support app blocks can't show the **Bundle Page** or **PDP Bundle Box** blocks.

The quantity break dropdown on product cards needs cards that include a quantity box and an add to cart button. Product pages and checkout work on any Online Store 2.0 theme.

## Review apps

Star ratings in the bundle builder come from your products' rating metafields. Judge.me, Loox, Okendo and Yotpo all write the standard ones. See [Show badges and star ratings on product cards](https://help.attravo.com/bundle-builder/articles/show-badges-and-star-ratings.md).

## Discount apps and codes

Bundle discounts are exclusive by default, and the quantity break discount is set to combine. When another app's discount or a code is in the cart too, Shopify's combination rules decide what applies. See [How bundle discounts work at checkout](https://help.attravo.com/bundle-builder/articles/how-bundle-discounts-work.md).

## Cart drawers and cart apps

After a shopper adds a bundle, the app opens your theme's cart drawer, or the drawer of a cart app it recognizes, and refreshes it. If your theme has no drawer, shoppers go to the cart page.

If a cart app changes prices or adds upsells on the way to checkout, choose **Go straight to checkout** under **After adding a bundle to cart** in **Settings** > **Appearance**.

## Other bundle apps

Running two bundle apps on the same products can give shoppers two offers for one item and confuse their discounts. Use one app's offers per product.
