For Sale ads are placed by people to sell things. They are NOT there for you all to make remarks on. I dont care if the item is way over priced or a bunch of crap, keep your mouths shut. If it doesnt sell they will realize why.
The next remark I see on an ad, the person will be banned for a week
If you want to ask about something in an ad, PM the seller
If it is a wanted ad, and you have what the person is looking for, replying is fine...discuss the prices in PMs
