Stamp collecting

So ironically, you'd be using a stamp worth a million quid, and the recipient would still have to pay excess postage.

A cunning plan without any downsides

I should clarify that I don't collect stamps, and I'm not thinking of investing in them. Just asking out of curiosity.

Used to collect British stamps as a kid though, and have a big fat album with most of those issued between about 1910 and 1970.

That's a good idea. My kids used to collect stamps, still got them in the attic. Have to check if anything worth a fortune.
