You are correct. But you can get an approximation of this.<BR/><BR/>Let's say you go to Amazon and find the lowest available price for X game. It is $10 today. You go back tomorrow and the lowest priced item available is now $11. Either the $10 item was sold, or it was removed by the seller or price was raised by the seller. Since people list on Amazon to sell their items we can assume for the vast majority of cases the item sold. So we can say on that day the price was $10 because someone listed at that price and bought at that price.<BR/><BR/>What if instead the price is $9 the next day? Either the seller lowered their price or a new seller came in with a lower price. We don't know if they $10 item sold, but we do know that seller's think their items are worth less money. So we can say the price went down. <BR/><BR/>Maybe buyers are only willing to pay $7. So that $9 item will stay at this price and never get sold and my price would stay the same, but eventually someone comes along at a lower price or the seller lowers it themselves until the price gets closer together and reaches an equilibrium. Because of this we can approximate the lowest price available on Amazon as the "market" price for that item on Amazon because items should be in a state of equalibrium with supply and demand. <BR/><BR/>My prices are not exactly Amazon's lowest price. But this is an example of how the Amazon price could be used as an approximation for the sale price.JJ Hendrickshttp://www.blogger.com/profile/12332952027760872601noreply@blogger.com
