Bunting's a-hanging, patriotic picnics are planned, and 'union jack' is the colour scheme de-jour. On the run up to the Queen's diamond jubilee, Brits are buzzing with pride for their monarchy.
Shops are keen to cash in on the burst of royal feeling, with all manner of clothes, food and household items regaled in red, blue and white.
Clearly royal revelry is not just an excuse for a good knees-up but also a chance to make a profit. Brits are expected to spend £823 million on Diamond Jubilee memorabilia so now is the time for ordinary folk to invest in a valuable keepsake.
According to Access Self Storage, the top items Brits will be buying is bunting and union jack flags. But such throwaway items are unlikely to bring home the bacon.
For perspicacious patriots the purses will come out for different memorabilia, carefully hoarded and preserved for future generations.
Iain Michael Brunt, expert and owner of Antiques.co.uk said: "Commemorative plates, mugs, original paintings, coins and stamps are likely to hold their value well beyond this weekend.”
Rare is the name of the game so bargain-hunting royalists should keep their patriotic eyes peeled for unusual matching items, (but interestingly Prince William pieces are more collectable than Prince Harry - he is a future King after all.)
Portraits preserve their value, so if you want to indulge in a commemorative tea towel, make sure it's adorned with a royal face.
Younger royals have more market value than older members of the majestic family, despite it being Her Majesty's special day.
Royal diehards have already made a mint out of the William and Kate's wedding. The gold coin issued for the Duke and Duchess of Cambridge's engagement is now worth 70% more than it sold for almost a year ago.
Due to the stable price of gold and collapsing european markets, the royal engagement coin which sold at £1,750 at the time of their engagement now sells for £3,000, reports the Telegraph.
However the top tip is go for quality over price. After all as the slideshow below shows - diamond jubilee thong, anyone? - there's an awful lot of tat out there.
