Head to West Norfolk if you want to shop like a Queen.
They include a butcher, a baker - and while there's no candlestick maker, Her Majesty also buys dress fabrics, clothing and hats in King's Lynn.
Business can apply to become warrant holders after they have supplied the Queen, Duke of Edinburgh or Prince Charles for more than five years.
Our map shows the 50 or so Norfolk firms which supply goods to the Queen and the Sandringham Estate.
The Queen gets her bread from Smiths the Bakers, in King's Lynn's London Road, where a large load will set you back £1.70. Filled baps start at £1.55 for when one wants to grab something on the move.
Gayton-based butcher JE Howard is also a warrant holder. The family firm sells beef from rare breed red poll cattle reared on the Royal Estate.
The Queen's also said to be partial to chicken salad - fillets are £7.26 per kg at Howard's.
While some Royal Family members are keen salmon anglers, the lakes at Sandringham are stocked with muddier-tasting carp. Warrant holders Coles of King's Lynn sell the king of fish - along with shellfish from one's doorstep in The Wash.
One long-standing warrant holder is Norwich-based fruit and veg supplier D&F McCarthy, which delivers produce to Sandringham when the Queen is in residence.
The Royals have been keen on growing their own since King Edward VII invested some of his racing winnings in new gardens. They can stock up on brassicas and beetroot at Fakenham-based warrant holder Norfolk Seeds.
While at Sandringham, the Queen likes to dress for the country whether she's out riding, picking up on a shoot or walking her corgis.
Country couturiers George Goddard of King's Lynn keep her clad in tweedy attire.
If one gets locked out, Lynn-based Magpie Security Services can let one in.
And if the Aga goes on the blink, one can call out Simon Ridgway, who has a warrant for servicing cast iron cookers.
