Why not?

I had a bunch of those ghost items.. almost got rid of them now lol but some did expire...

Perhaps add another mechanic too with the following note..

Note: Listing an item for 14 days will incur an additional 50% gold cost & 2 Platinum.
e.g listing an item for 14d at 100,000,000g costs 7.5m + 2p. (Instead of 5m)


thanks
