# Why does my widget have its own 'Add Offer to Cart' button?

It depends on your theme. Some Wix themes don’t support webhooks yet (we will let you know as soon as it is changed) — but the good news is, they still work well with the Fab Bundle app 🎉

In these themes, the widget will be added along with its own "Add Offer to Cart" button, so your customers can use it to add products with offers to the cart.

{% hint style="success" %}
The Fab Bundle app works with both Wix themes that have webhooks and those that don’t. Depending on the theme, the app’s widget on your product page will either have its own 'Add Offer to Cart' button or use the Wix native 'Add to Cart' button.
