You need to name a price. Rule #10
10) For Sale threads need to have a price listed, if you are unsure of what you want to ask for an item list a price you think is slightly higher than what you want to get and simply state, 'willing to negotiate'. You can also add 'OBO' (Or Best Offer) after your projected price. While this means you are willing to entertain offers it is NOT a license to auction, neither does it mean that it is acceptable to take a higher offer after you have agreed to a price and a deal.
