If it ever turns up, I could well imagine him being skinflinty enough to try to send it by 2nd class envelope and then in two weeks the recipient gets a note through the door to tell them Royal Mail are holding it hostage until they pay the remaining postageI'd love to see what these look like when they come through the letter box. I can just picture him now, folding it up with his tongue poking out, then trying to stuff it into an envelope with his fat sausage fingers. You just know it'll be the least professional operation in history. He used to delight in taking the piss out of working class women who try to bring in an extra couple of quid by selling things like homemade Christmas decorations. That's what the whole "Remove if not aloud TIA XXXX" reference is all about.
I was rich enough, I'd order a custom one that says "Simon Harris is a talentless grifter who conned the people of Essex out of half a million quid in exchange for running some shite Facebook groups", just to see if he'd print it. I like the whole 'here's a tenner, now dance for me, witch' vibes.
