I've been looking at PS3's for sale on eBay. The cheapest one went off at $380, brand new in box. It happened just a few days ago.
Does that make the market price of a PS3 $380?
Harvey Norman, Kmart, Big W, JB and DSE sell the same model for $600 - $700 and make bugger all margin on them.
If you wanted a PS3 and took $380 as your market price you'd be searching for a PS3 for months and never get to enjoy one. They regularly sell on eBay for $500 buy it now.
In fact, Sony sell the hardware at a loss in the first place...
On that minute and on the ebay market it was, but the fact that that seller (or other sellers) has no more listing for $380 and buyers are willing to pay more than $380 since then means the market has moved up. Market price is a volatile thing and does not neccessarily reflect the long term value or future price of an item. Just take sharemarket for example, the market price of a share goes up and down every minute. BHP was $25 close of today, it was $40 just a month or two ago and who knows where it might go in future. For argument sake let's say it goes up to $30 tomorrow and you no longer can buy it for $25, are you going to argue that today market price for BHP wasn't $25?
