I think homegrown is right, everyone thinks their item has a higher value than the next persons. I personally love the barter section, I was on the barter section like 10 years ago before people knew what bartering was. I used to make beanbag toss games aka cornhole games. It probably cost me about $12 in supplies to make a game but this was before every store was selling cheap plastic and bolsa wood crap versions. The only way you used to be able to find them was driving down the road and seeing them in someones yard or maybe at a flear market. They went for anywehre from $75 to $200 depending on the type of wood, hinged or not, designs, lights, etc.
Anyhow, I used to trade them for all types of good stuff, great tickets to sporting events and concerts, etc. Basically what cost me $12 in supplies I could trade for almost $400 worth of tickets. Why? Because one mans junk is another mans treasure. Most of the guys I traded tickets with got them for free from work so the tickets meant nothing to them in terms of csot but a beanbag game for their tickets was a $100 item tehy didnt have to spend a penny out their own pocket for. On the other hand I could take my gf and a few buddies to a sporting event that would have cost $400 and it really only cost me $12 and an hour or two of my time.
Bartering can be a pain but you can often get more bang for your buck than selling. The thing that annoys me is the people who dont have one item worth anything so they try to send lists.
For example...Sorry I dont have $500 to buy your motorcycle but I do have....
1 laptop plug for a hp netbook
lamp
dog crate
origional xbox
3 playstation controllers
ipod nano
and basically just give you a long list or random and worthless crap
