Maybe you'd love to get your hands on one of those one-eyed Olympic mascots or bibs worn by members the Canadian women's soccer team in their bronze medal game.
Don't despair, you can find loads of tea towels, mugs, plastic London buses and T-shirts on the London 2012 auction site, but you will also find some rather suspect items if you browse ebay.
According to England's Independent newspaper, some vendors are offering bottled Olympic air - one of them claiming to have been "collected at the entrance to the Olympic Park only days ago."
That one, the paper says, has yet to attract any bids.
One seller put an optimistic starting price tag of £49.99 ($77.71) on an empty plastic water bottle that could be bought immediately for £99.99 ($155.45) otherwise.
There was even a crumpled tissue on offer.
"This was the tissue I used at the 2012 Opening Ceremony to wipe the seat with, it has some of the molecules of the Olympic atmosphere attached to it and I shall be sealing it in a plastic wallet so you can show it to your Grandchildren and so on," declared "captainjay1701".
Not surprisingly, no one expressed interest in that item either.
The Independent says the auctions are following a precedent set by the Games organizers themselves, who are selling off various items used during the Olympics.
The Mary Poppins costume used during the opening ceremony has attracted a high bid of £255 ($396.45) with one day to go in the auction.
A hockey ball used in men's gold medal game has a similar period to run and has attracted a bid of £335 ($520.82), whereas the netting used in the men's gold medal basketball game is set to go for at least £1,805 ($2,806.25).
There is even memorabilia from the last London Olympics which was held in 1948.
One of the torches used in the relay has a price of £14,000 ($21,765.94), although no bids have yet been placed with 20 days until the auction closes, according to the paper.
