I see the classified ads section just got a bit more interesting last night 
I have a bucket of steam for sale made from the tears of unicorns (metric only I'm afraid). Please pay me in used nine bob notes, washed dollars or gold. Generous discounts available for the illuminati – make yourselves known to me in the usual way.
International shipping available up to the 31st January, after that please arrange your own couriers as I'm blowed if I known what will be happening then, unless you live in Tonga, I hear we have a trade deal in place with you…
