Postage calculator

Hi - I have signed up for RomanCart as the shopping cart for the website I am making (selling secondhand books). I would like to add a feature that would automatically calculate the postage charges depending on the number of books, destination (ie within Australia, or overseas), and type of mailing priority selected by the customer in the shopping cart. Could anyone please point me in the right direction as to what is available, and how it would integrate? Thanks!

Thanks Adele. It appears the answer was right under my nose.
