King Charles III’s coronation in London on Saturday marks one of the most important moments in the modern history of the British monarchy.

Everyone wants a piece of the action.

Royal fans and far-flung visitors have been lured – and fascinated – by the ceremonial spectacle of the monarchy, with tour companies, shops, hotels, supermarkets and restaurants cashing in and laying out the red carpet.

Whether it’s a decked-out bus tour of London’s top sights boasting high tea, booze, meals or merchandise running from regal to kitschy, there’s a party and memorabilia for every taste.

Massive spend

All up, families and tourists are expected to spend £1.4 billion ($2.6 billion) in the run-up to the ceremony, reported the UK’s Sun newspaper.

Whether it’s tasteful or tacky, let’s narrow it down to the spend on merchandise – a massive £245.91 million ($462.5 million), according to the tabloid’s estimates.

Residents have decorated their letterboxes in hand-knitted purple crowns, you can buy a life-size photograph of the King to stick on your lounge wall next to the TV, and you can even take a ride on the London Eye to get crowned in a sky-high photo booth.

Supermarket chain Aldi is selling coronation coleslaw to go with the spinach and broadbean coronation quiche, and its own king and queen of vegetables just in time for the party – limited-edition knitted Charles and Camilla Kevin the Carrots for £3.99 ($7.50).

Morrisons grocery chain is selling ‘God Save the King’ banners and dinner-plate size cookies with ‘Party Like Royalty’ written in icing, while Heinz changed the name of its tomato ketchup to Kingchup (don’t worry, it’s a 570-bottle limited-edition run).

Not to be outdone, Tesco is selling cheap coronation teddy bears – including the coronation London guardsman bear for £6 ($11.20) or the king coronation bear for £10 ($18), and there’s also a coronation Jack Russell door stop for £12 ($22.50) and a £3 ($5.60) inflatable crown.

MyLondon writer Lea Dzifa Seeberg took the tube to Buckingham Palace, and walked around the shops to find the weirdest stuff for sale.

She found a very expensive limited-edition £300 ($564) coronation teddy bear, a £150 ($282) pair of champagne flutes and £9.95 ($18.70) bobble-heads “that made the King dance a little every time the sun hit him”.

She found “[a plate] emblazoned with the coat of arms, lots of garlands and other scribbly things, [and] one of the suckers cost £195 ($366) despite being barely big enough for a slice of cake,” she wrote.
