POSTAGE FOR THIS ITEM: (uninsured): UK first class free, Europe & overseas £4.00. Packages with total value over about £50 need to be insured, except by prior agreement. Benefit from free postage for any additional items in the same package, subject to weight and maximum value. A certificate of posting will always be obtained by me for every package posted. I always try to use obsolete commemorative or definitive stamps when I can, but please note this is not usually possible for registered mail. For anything other than low-weight unregistered postage, particularly multiple purchases, please request a combined invoice from me before making payment.
