Go to your thread, go to Administrative and hit delete.
If those are site rules, then fine. I personally utilize threads with items that have already sold to gauge to current used market price for items I am looking to buy or sell. I wish people would not change the price to "SOLD" after an item sells.
or consider doing as archerytalk and some other threads do and just lock your thread so you can tell its dold before clicking on the item, i also like being able to see current market
