When trading for items and trying to keep the trades as close to an equal value as possible, you have to remember that you may see an item as "cheap" while the person offering sees the original price paid. For example some of the DVD's I've seen offered ran a good $30 bucks new, it isn't fair to see that offer as only worth a couple of bucks.
Swaps can be so much more fun if everyone plays nice and doesn't have the idea that everyone else is trying to take advantage of them.
