We need to send from HK to the UK a paid-for stamped envelope so that our documents can be returned to us from the UK to HK.
How can we get UK Royal Mail stamps worth ~£8-10 in Hong Kong so that we can prepare the return envelope and mail all our documents together?
Is there any kind of little shop in HK offering a service to sale stamps for the UK?
We will ask a friend in the UK if they can purchase them and mail it to us, but this will take time, and we're on a tight time limit as the documents are time-sensitive.
We also asked HK post and they only offer an international voucher which can be redeemed at Royal Mail for stamps, but we're concerned that this will be disregarded by the UK consulate we're sending the documents to (they won't be bothered to go to a post office and exchange it for the stamps... they're lazy bastards!).
Or do any of you out there by chance have stamps worth this much that we could buy for a premium?
