Dear Sir,
I am writing to inform you that a tiny tiny jar of Marmite costs 4.66 euro at my local supermarket.
However, I will be more than happy to get you some if this helps you start an Internet Affair with someone in the vicinity of Hull that shall remain nameless, so that I can both blackmail you afterwards, and get loads of money from that to buy even more Marmite.
Regards and looking forward to business together,
Johnny "Cupide Cupid" Marrmite.
