I find very few people know how to effectively sell on ebay. Those with the best pictures always sell at a premium. And cheap buyers rarely buy from them. The opposite rings true, cheap buyers can buy cheap when the the pictures aren't clear because those willing to spend for what they want won't take a chance.

I would call most sellers on ebay motivated by laziness. They do the least possible. They don't realize that 5% more work will yield a greater than 5% profit.
