If his item was truly highly underpriced then you would be looking at it as an opportunity to buy and flip the item for profit. Since you aren't it is fair to assume you are overpriced. If I know that that horn will sell at 1.2mil I would be for sure buying the one at 900k and making an easy 300k (minus taxes) profit. Sounds like you are just whining because you didn't get to overcharge someone. Boo freaking hoo.
