This is wonderful!!! I have been Postcrossing for years and it's so much fun to get a postcard randomly out of the blue from someone. Regrettably the cost to send a postcard international from the USA is over $1 now, and the cost of a postcard means you might be spending around $2 per card, but it's so worth it.
Well, if you buy N of these global forever stamps, the cost will just get cheaper over time (inflation).
Since the non-postcrossing Global Forevers are circular and a bit annoying, I use 2 Forever stamps plus a 20¢ stamp (6¢ wasted - i suppose i could switch to 15¢ stamps...).

Not if you buy them today to use later I would think. Since you gave up the $$$ today, it won’t do anything for you anymore even if you don’t buy another stamp again I’d think. Compared to buying a stamp whenever you need one in the future but not tying your cash up until that moment.
