I need to send some docuemtents in a postal tube to the USA and need to pre-pay for the return of the package. I was told to buy international reply coupons but on the Royal Mail website it says they no longer sell these?
or telephoning your local Royal Mail customer care centre to see what advice they give ?
It might be that you will have to send the postage cost over to the recipient in the US and they will have to post it themselves . Reply-paid postage over international borders sounds a bit awkward - but good luck with it anyway .
Has the person / organisation in the USA got a paypal account ? If so it is a very easy and cheap way to pay the postage costs. Paypal can be used for any payment not just ebay items.
i used to use IRC's 20 years ago when writing to family history contacts across the globe, they were a way of sending postage to other countries for people to reply to your enquiry, I think they died a death with the invention of the WWW.
