I don't understand the satire, can you explain?

We can't see the full set of "lower denomination" stamps on the letter, but I'm not 100% sure it's actually lower denomination. The sender of the stamps seems to be using the "2 domestic forevers + some amount of cents = 1 global forever" formula. I think the UK sender didn't need to include _two_ global forevers.

Indeed, the formula is correct. Wikipedia maintains a list of historic Forever pricing: https://en.wikipedia.org/wiki/History_of_United_States_posta...

From the blog, the letter from California was dated April 2022, at which point the rates were domestic = $0.58 and global = $1.30. So the California sender correctly attached two domestics valued at $1.16 total plus an additional $0.14 to make $1.30.

It would be hard to know that ahead of time though. The global forever stamp is good for letters up to 1oz which can be as little as 4 US letter pages. It took the FSF 5 double-sided pages. Granted, it looks like lightweight paper & the post office doesn't seem to be very picky about this. But I think sending two forever stamps was being on the safe side.

I think quoting that part alone, didn't make it clear I was referring to the whole article.

May have been more apt.

Is eBay really anyones first thought when looking for a (non-collector) stamp to (actually) mail?

Perhaps he should have picked up a few £1 coins on eBay, use them to purchase some stamps from the post office?...
