I think people are just jealous they didn't think of this
If you've seen the show on TV, you know that there are lots of reasons why people will trade/buy things that are worth more for something worth less. I don't see any reason why that should surprise people on here or upset them. Not everybody buys and sells solely based on value. They often have other wants / needs that are more important at that moment.
If you don't want to watch or play, then go ridicule someone somewhere else!
