How to send SASE to UK from US?

Sending auto requests to the UK, how do I pay for return postage?

Assuming you can’t by UK stamps someplace, I think the only thing you can do is send an international reply coupon.

The USPS doesn’t sell international reply coupons any more.

Damn. They don’t. Just Googled it. Stopped in 2013.

So, really, what are you supposed to do? Send an international money order? (Which the USPS still sells.)

Perhaps a stamp dealer could sell you recent UK stamps. (They would cost more than face value, but still.)

BTW, the OP refers to “auto requests.” What is that?

I don’t know if it works from abroad, but I can print my own stamp from Royal Mail’s own site. http://www.royalmail.com/personal/sending-mail

If it does work, you could print it on to a self addressed envelope and solve the problem.

Buy some pound notes and include a couple with the request and the envelope.

I would guess an “auto request” is an “autograph request”

Note the International Money Order is accepted in very few countries–and NOT in the UK:

Anguilla
Antigua and Barbuda
Bahamas
Barbados 1
Belize
Bolivia 2
British Virgin Islands
Canada
Cape Verde 2
Dominica
Dominican Republic 2
Ecuador 2
El Salvador ($500)
Grenada
Guinea 2
Guyana ($500)
Honduras 2
Jamaica 3
Japan 4
Mali 2
Montserrat
Peru
Saint Kitts and Nevis
Saint Lucia
Saint Vincent and the Grenadines
Sierra Leone 2
Trinidad and Tobago 3

Anyway you don’t want something which is a pain to handle for the recipient. So I would agree with a mailing label and a couple pound notes.

Paying by Paypal, and getting the recipient to print a Paypal label is by far the most hassle-free method for both parties.

Not if one or both parties don’t have or want a PayPal account.

He’s ordering a Bentley, and wants it mailed to him in the US by return postage. That’s his difficulty – it’s a whole lot of postage stamps to deal with.

If it’s England or Wales, they don’t have pound notes: the smallest notes are five pounds. Scotland does have one-pound notes, but they might be hard to buy in the US.

One-pound notes are rare even in Scotland - only RBS still prints them - but they don’t seem to print very many, and ATMs don’t dispense them. I think I’ve seen one in my change this year?

I tried this, without quite completing the process. It seemed to be possible to use it even with an IP address clearly in the US.
