Having a powerful weapon on sale at 10% if buyer didn\'t pick it up is sort of unbalancing. This allows some player to just camp by bargain bins and keep clicking refresh until something interesting shows up.
An idea is that after the designated time for the buyer to pick it up expires. The said item goes into the bargain bin at the price the buyer pays. And at a set time limit (one day in real life might be good, or four times in a real time day, depending on what the developers want). The price is reduced using a percentage.
Exampe...
An auctioned sword that was sold at 10,000 tria expired.
The \"unclaimed\" bin holds the item and sold it at 10,000 tria.
After a period of time, the price is by 1% of the original price.
So after one time period, it\'s 9,900, and 9,800, and 9,700 and so on.
After a certain time, let\'s say if the price is down to 50% the original and no one bought it, it disappears forever.
