Hey - How do I show shipping charge at product page or at least when you add to your basket?

Is there an app for my UK site www.snugcornwall.com that will avoid saying 'Shipping will be calculated at checkout'. That can put customers off and has been fed back to me at testing stage that they'd rather not wait until checkout to know (even though I have a shipping page) it all seems rather convoluted. Thanks
