Unfortunately, I have no idea. In the US it would most likely come back with "Postage Due" written on the envelope, but I have no idea how it works with overseas mail.

Thanks packrat!

Unfrotunately, it seems that I have therefore sent out three SASEs with underpaid postage to the tune of 8 cents - curses!!!

So that leads me to another question... Assuming the celeb doesn't add the extra postage (which I wouldn't expect them to) would it make it back to the UK? I'll happily pay a Royal Mail surcharge, but will it make it into the UK to allow me to? Any thoughts?

Many thanks!!!

Actually, re-weighing a replica of the contents, I might be lucky enough that it falls into the weight category below - will keep fingers crossed! Would still be obliged for an answer on the above question tho, just out of interest! :0)

It would fall under the category of "Large Envelopes (Flats)" on this page here: http://www.usps.com/prices/first-class- ... prices.htm

Hi to all the US collectors!

I'm from the UK and struggling with the USPS website (this is before I have to phone them to make an order!)

Can anyone tell me whether an A5 envelope falls into the 'Letter' or 'Large Letter' category (it's not a rigid envelope, and I can work out the weight; it's just the size also affects the price, and I don't want it sent back for the sake of a few cents postage, but equally dont want to waste money excessively overpaying!)

Much obliged!
