Free product with shipping

[mobimob]

Hi all,
I have a site, where people can put a free gift in the basket(zero amount). They should only pay for the shipping on the item.
But....My product is zero amount, and theres a fright set on the product.
But the shops dosent show any shipping price when put in the basket.
That no good.

How can a I charge shipping on a product, that costs zero dollars/kr?

Hope that someone has a hack or can tell me how to do it.

Hope to hear from yu all

Best regards,
Mobimob
