Payment for UK buyers is by Bank transfer (please Email me for bank details), Paypal, or UK postal order. FOR BUYERS OUTSIDE THE UK, PAYMENT IS BY PAYPAL ONLY.
For international buyers, whilst I normally send by Airmail, I will do surface-mail on request; I do not offer this as standard because it can, and does, take up to 5 months by sea ( and worse if we consider the problems of pirates and hurricanes in some parts of the world!). I know that it can be quicker than that, but it's a gamble that often does not come off.
For some reason, a few people seem to be increasingly using PayPal echeques. Please note that these usually take 11 days before PayPal actually clear them. My advice is to not use this service because of this delay.
