The amazing thing is that he is usually the cheapest on a given card.
In regards to a cheap refractor, if it's the only one on the site I will price it $2.75. Prices have to be slightly higher given submission fees and monthly storage fees. Yes, there is room to negotiate. By pricing it up, we are hoping someone just buys the card. Plus, with Amazon we are possibly loosing 20% and then another 20% when cashing out. So, I most cheaper cards I will most likely will accept or counter all cards at 20% off. Pretending they sold on Amazon.
