To accelerate buyers and seller finding each other and the right deal.
Both buyer and seller when going online and advertising or searching a product (their flat, car etc.) will specify not just one price, but 3 prices. The advertised price, the lowest price they might accept, and a price between these two representing what they really would consider an immediate deal price. The system (machine or human) will try and match buyer and seller based on these 3 parameters.
From time to time, there is an auction for a meeting or talk with a pubic figure. The problem with this auction model is, that only people with money can contribute and only they can win the auction.
Instead of one person donating a large sum, have people donate smaller amounts (or larger ones if they want), and instead of an auction, have a raffle and a winner. Each person donating has the same chance, and you get all of the donations for the charity.
