To receive postage discount please place the items in the shopping cart and request invoice total before paying. If buying from overseas, please use the B1D.co.uk site to make your purchase.  Due to B1D's refusal to refund seller's fees associated with refunds I do not issue post-sale refunds for overpaid postage.  If in doubt please ask!  I always obtain proof of posting on my items.  For insured delivery please select Special Delivery or insured option when buying. Default postage option for UK is 2nd class but 1st Class also available as option.
