Not all items on ebay are sold. These probably fall into two categories, those that no-one wants, even at a low price, and those for which too high a reserve has been fixed. It is clear that these auctions fall into a different category from those where a deal was arranged. For this reason they have been analysed separately. I have tried to identify all manufacturers with sales of 5 or more rules.
Some rules also appear on ebay sites for the United Kingdom, Germany, Canada and Australia.
Prices are presented in dollars for the sake of comparison but have been converted from the original at current exchange rates.
