You can just buy them in Royal Mail webshop, it's not a problem at all

Under the UPU guidelines PO's must accept IRC's for exchange/redemption, not sell them i'm afraid.

Many countries including the US no longer offer them for sale.

OP I suggest you check out http://www.royal-mail.com which is the UK post office, all the information you need is there. Alternatively browse this section of the forum because your questions come up alot {up}

Hello!

I live in Madrid City and your Post Office should sell international reply coupons because the US is a member of the Universal Postal Union (www.UPU.int). In my view you have to write to USPS (Customer Service) about this issue

I hope to have been of help.

The best of luck

Hello everyone, I live in the USA [us] (In the state of Wisconsin to be more specific) and I wanted to mail off some autograph requests to celebrities whose fanmail address is located in the UK [uk] (for example Matt Smith) Anyways I wanted to buy UK stamps but I don't know where, I also don't know how many UK stamps I would put on a envelope if I had them in hand. I would be mailing off standard sized envelopes as pictured here http://ecx.images-amazon.com/images/I/317ojNuXirL._SY300_.jpg with another standard sized envelope folded inside, a letter, a 4 by 6 photo, a blank white index card and $2.00 since the post office no longer sells international reply coupons. Also how many stamps would I need for a 8 by 10 envelope with a 8 by 10 envelope folded inside, a 8 by 10 photo and letter? Thanks so much
