Thread: Upsell Items (no shipping)

Is there anyway to define a scenario like this?

Customers adds product X to the cart. We then show them products a, b c& d and tell them they can add these to their cart with no additional shipping cost?

The only built-in way to do that would be to create the upsell products as free shipping products, and that would apply whether the product was added as an upsell or not. You could do a little custom work to make that only apply to upsells.
