Estimates are that consumers will spend between 40 million pounds to 70 million pounds ($54 million to $94 million) on royal wedding-related merchandise, including commemorative mugs, plates, coins and posters.
If you're tucking in to watch the wedding from home but want to feel "part of" it you can enjoy a bowl of "Wedding Rings" cereal, featuring Prince Harry and Meghan Markle on the box and sold online for only 35 pounds ($47). It promises to be "royally good." There's also "Harry" and "Meghan" Marmite, if you can choke that down.
Britain's Heck food company has created special pork sausages including the ingredients of "sweet ginger" for Harry - a nod to his famous red hair - and "American mustard" for Meghan. At 3 pounds ($4) a package, they're available at Sainsbury's grocery stores around Britain.
KFC's Royal Wedding-themed buckets, complete with the company logo in gold, were allegedly inspired by Harry's confession that he proposed to Markle while preparing a roast chicken. The reverse side reads: "We declare a regal day of celebration, jubilation, and fried chicken." They're available in limited quantities only at KFC Windsor on Saturday, the royal wedding day.
After enjoying the chicken, you might want to try the Windsor and Eaton Brewery's "Harry & Meghan's Windsor Knot" pale ale, which boasts barley grown locally on the Royal Farms in Windsor and retails for 2.25 pounds ($3) a bottle.
The company says "marrying" together a combination of British and American hops and champagne yeast "creates a new pale ale that is young, fresh and full of character." For those with a sporting bent, royal fans can shop online for a Meghan or Harry one-piece lycra women's swimsuit offered by the gift store Bags of Love.
For 28 pounds ($37.70), the suits are available in sizes from XS to 4XL and promise to be "soft, stretchy and supportive." They also display enormous faces of either the bride or groom across your torso.
For those already in the mood, the Crown Jewels Heritage Condoms company (yes, it's real) is offering a box of Royal Wedding souvenir condoms for 10 pounds ($13.50). When opened, the consumer is treated to a pop-up picture of Harry and Meghan and the slogan "your prince will come" as an arrangement of "God Save the Queen" and "The Star-Spangled Banner" plays in the background. A certificate of authenticity makes the packet complete.
