With the Flux theme, you have the option to offer a specific product directly in the shopping cart.

This is a great way to cross-sell products or services that may be valuable to your customers, regardless of what they are purchasing. For example, you could offer a branded t-shirt or a gift wrapping service.

To set it up:

1. Go to Theme Settings > Cart and enable the cross-sell feature.
2. Select the product you want to display in the cart.
3. Optionally, add a heading to encourage customer action.

For products like gift wrap or other cross-sell items that you don’t want to display in product listings or collections, you can hide them by using the “hide-product” tag.
