Postage and packing charges are listed separately for each item in our shop. If you buy multiple items then the combined postage and packing will probably be less than posting the items individually. However, because of the wide variety of goods we sell and the complexity of the current Royal Mail Pricing in Proportion rules, it is not possible for us to set formulae for this in the shopping basket.
If you decide to pay by PayPal then any overpayment on the combined postage and packing charge will be refunded after we have posted the goods.
Of course, if you would prefer us to quote for combined postage and packing before you buy then please e-mail us.
