Why are my Cart Upsell Suggestions not working?
Last updated on October 22, 2026
Check these first:
- Open the offer and make sure Cart page is turned on under Placements, then click Publish. It is off by default on new Volume Discount, Product Bundle and Buy X Get Y offers.
- Make sure the cart meets the offer's conditions. For example, a Volume Discount suggestion shows only when the units still needed for the next tier are no more than the units already in the cart, and a Product Bundle suggestion only when at least half of the bundle's products are in the cart. See Displaying upsell suggestions in cart for every offer type.
If both are fine, the cause is usually the theme's cart page. Vitals places a suggestion under the matching cart item by finding that item's link to its product. If your theme shows cart items without a link to the product, the suggestion can't be placed there. Contact our support team: we can often add a setting for your theme so the suggestion finds its place.
The Cart page shows only one offer for each item in the cart. If another active offer for the same product has its Cart page placement turned on, such as a Volume Discount, Product Bundle, Buy X Get Y, Related Products or Product Add-On, it may show instead of the offer you want to see in the cart. Offers targeting specific products take priority over collection or All products offers; at the same targeting level, the offer with the larger discount usually takes priority.
To show the offer you want, open the competing offer and turn off its Cart page placement, then click Publish. The offer can remain active on the Product page, and its discount will still apply in the cart and at checkout when the quantity qualifies.
