Anyone else from the UK buy US $ from the Post Office?

[MARKAEL MYERS]

Was wondering if anyone else on here buys US $ to use as return postage?
I have done so on several occasions as IRCs are no longer available (at least where I live anyhow), and had a few returns. I'm not the biggest fan of doing so as the PO staff are often over interfering/smirking when I go in to ask.
I do use US stamps via ebay etc, but sometimes $ are easier. I'm curious to what some of you guys do?

I always use US stamps, purchased from Bri0626 here on the forum.

You'll save a lot of money if you just stamps since your smallest paper bill is a 5.

OP is in UK talking about buying US$ currency.

Nothing to do with our £5 note...

oops! I thought he meant if it was easier to get stamps or just send over money. lol Rereading I see that he means exchanging for US $ or getting stamps. #fail
