If you are looking to get rid of something but don't really have a set price in mind, you may want to consider AUCTION rather LISTING...
Click on mouse over VDR STORE and click on CLASSIFIEDS in the top Nav Bar.
Click on ACCESSORIES
Then from the nav bar select either ADD LISTING which will sell your item at a set price, OR Click on ADD AUCTION. You will be able to set a Reserve Price, a Buy It Now price and a Start Price. Auction is the best way to do OBO type stuff.
