Copies of the Prince of Wales and Duchess of Cornwall's marriage certificate have been made available to buy for the price of �3.50. Those interested are being urged by staff at the Guildhall in Windsor to move quickly before the price goes up.
When the current registry book fills up and the certificate is sent to the archives the price of a copy will double to �7.
The couple married in a civil ceremony at the Guildhall on Saturday.
Deputy registrar Marilyn Macaluso, who is dealing with requests for the nuptial papers, said: "No mistakes were made filling in the entry on the register on Saturday.
"It went beautifully."
Marriages dissolved
On the certificate, formal witnesses to the civil union were listed as their sons, Prince William and Tom Parker Bowles.
The couple's names are put down as His Royal Highness Prince Charles Philip Arthur George the Prince of Wales, aged 56, and Camilla Rosemary Parker Bowles, 57.
Both state their previous marriages as dissolved.
The Duchess left the column denoting "rank or profession" blank while her husband described himself as "prince of the United Kingdom".
