2 small letter first class stamps = 1 large letter stamp?

Well 2x36p = 72p and a large letter is 52 so as long as you don't mind wasting the extra 20p then go for it. As long as it makes 52 then it's fine.

You could buy the correct postage omline here http://www.royalmail.com/portal/rm/jump2?catId=400043&mediaId=26800663

But 2 letter stamps at 36p = 72p, assuming your large letter is under 100g then the price would be 52p so ok to use 2 stamps, your just over paying but only up to 100g

Thanks for your replies.

I figured this was the case so have sent it off as I had an abundance of first class stamps anyway. I don`t mind losing out on the 20p, it would have cost me more in fuel getting to the post office to buy one! ?

Kppics - thanks for that link, brilliant, I hate going to the post office!! Don't know why I had never looked into it before

2 regular second class = one large doesn't it?

not that it matters now if it's in the post ?
