Over the past five years we’ve seen an incredible amount of items traded on Listia (over 100 million!) and we’re constantly amazed at the items people list. Just when you think you’ve seen it all, members find value in the most unique things. Today we’re excited to add one of the rarest items to ever be on Listia. We have purchased a wedding cake slice from Prince William and Duchess Kate Middleton’s royal 2011 UK wedding for $7,500 and we’ll soon be making it available on Listia!

Each day on Listia over 100,000 items are exchanged without money ever changing hands. Over 7,000,000 people from around the world explore the online marketplace to find collectable, useful and free things they love. We want Listia to be the place you go to find almost anything, from the exotic to the unimaginable, and perhaps even the most royal of gifts.

My co-founder James Fong and I started Listia with the intention to motivate people to declutter their homes while extracting value from the things they no longer use. There is no better motivation than the opportunity to acquire a once-in-a-lifetime collectors items without actually having to make a purchase. We understand not everyone can always afford to collect the things they love, but on Listia we want to take money out of the equation and give everyone an equal opportunity to pursue their slice of happiness.

The slice of wedding fruit cake is wrapped in a greaseproof paper and presented in special tin. The cake was made by Fiona Cairns and was presented to all the guests and dignitaries at the April 29, 2011 wedding. Written on the lid of the box that the cake comes in is “William & Catherine 29 April 2011.” With the box comes the official wedding card that reads “TRH The Prince of Wales and the Duchess of Cornwall / in celebration of the wedding / of / TRH the Duke and Duchess of Cambridge.” It also comes with a blank invitation to the royal wedding on Her Royal Highness Queen Elizabeth II stationery.

Our entire staff at Listia strives to bring great value to our members and unique items to Listia. In 2015, we hope to bring even more extraordinary once-in-a-lifetime items to Listia that will appeal to everyone who loves a good deal at a free price.

In April 2015, all Listia members will have a chance to own this delicious piece of history without ever having to be rich, royal or spend any physical money on the cake itself. We look forward to rewarding one lucky person with the honor.
