Wrong quantities or missing gifts when the theme redirects to the cart

Some themes have a setting that sends the customer straight to the cart page or checkout the moment they press add to cart. That setting conflicts with how bundles are added, and it can cause wrong quantities, missing free gifts, or only one item from a bundle reaching the cart.

Why this happens

A bundle is usually more than one cart line: the main product, any bundle products, free gifts, and upsells. Bundlex adds these together in one smooth operation while the customer stays on the page. When the theme force-redirects immediately after the first add, the browser leaves the page before the rest of the bundle finishes adding. The result is a cart with only part of the offer in it.

How to fix it

Turn off the redirect in your theme settings:

In the theme editor, open Theme settings and look for a section called Cart or Add to cart behavior. The setting is usually named something like "Redirect to cart page" or "Go to checkout after adding".

Set it to stay on the product page (often called "Show cart drawer" or "Stay on page"). Your cart drawer keeps working as before, and the full bundle is added correctly.

Still seeing partial adds?

If quantities are still wrong with the redirect off, another app may be intercepting the add to cart button. See using Bundlex with cart replacement apps, or contact us in the app chat and we'll check your setup.
