Ahh, so that is how that works.
I guess the difficulty is ensuring that the money is exchanged into english notes. I made the exchange at one of the post offices. Lol they did warn me that I should just spend all of the money.
Actually, i could exchange scottish notes back in the US but it was expensive. It cost me about $15 for each exchange. I still have a 20 pound note from one bank as it was not worth it to exchange it. I should have bought whisky with it.
Maybe someday I will go back and can spend it. Lol.
