How to show bundle offers in the cart (Integrate - Buy more & Save more)
Overview
Integrate - Buy more & Save more shows offers from XB: Bundles Quantity Breaks inside the cart drawer, right under the matching cart item. The shopper can upgrade the item to a bigger quantity, a bundle or add-ons without going back to the product page.
There are three integrations. Each one uses a different kind of Bundles offer:
| Integration | Bundles offers it shows | What the shopper sees under the cart item |
|---|---|---|
| Quantity Break | Quantity Discounts | The tiers, for example "Buy 2 Save 10%", or a one-line tip. Clicking opens the Buy More & Save More window. |
| Product Bundle | Fixed bundle, AI Frequently Bought Together and Buy X Get Y (BOGO) | The bundle with a Claim offer button, or a one-line tip such as "Buy more & Save more Save up to 22.26%". |
| Product Add-on | Product Add-Ons | The add-ons with a Claim offer button, or a one-line tip such as "Buy more & Save more Save up to 13.55%". |
