Postage / Shipping Costs:- For multiple orders please request an invoice. I offer a large number of oddly shaped items that can vary enormously in weight. It is impossible to calculate an accurate postage cost for orders of more than one item in advance. Requesting an invoice will allow me to combine postage where appropriate and offer the lowest price possible.
