advanced available book button calculate choosing copy costs create customer help letting option options overseas paperback postage prices rates sales sell send shipping system users

I would like to create a button to sell my book in paperback, which gives the customer the option of choosing between two different postage prices.

But I cant figure out how to do this. Currently I am simply trying to figure this out for sales within the UK. However your system looks very advanced, Is it also possible to make a button which would calculate how much it costs to send a copy overseas?

I am sorry but E-junkie currently has no way letting users choose between 2 shipping rates.
