On ebay a successful sale of an item will often prod
other owners of the

sellers see the first sale, which usually has a high closing price, and
figure that they too can obtain that closing price. However, Mr. Deep
Pockets already has his and isn't bidding on the subsequently listed
items and they often sell for significantly less than what Mr. Deep
Pockets paid in the original sale. Its supply and demand in action in
a microcosm. A sudden increase in supply pushes the price down as the
first "desperate" buyer is now out of the market.
Except when Mr. Deep Pockets insists on buying up every instance of
said item (or piece of a system). This has happened to me quite often.
