One thing it changes is that the former high bidder can no
longer leave feedback to the seller because technically the
auction was ended with no bids - thus there was no completed
transaction by Ebay's definition.

The second difference that it makes is in Ebay's rule that
once an auction is completed with a high bidder (assuming
any reserve price has been met) the seller *MUST* go through
with selling the item. If Ebay didn't require a seller to
cancel all the bids IN ADVANCE of the end of the auction in
the case of deciding not to sell the item, then I'm sure
you would have a lot of people winning auctions only to get
told: "Sorry, I don't want to sell anymore. Bye." Which is
what they don't want - they want a completed auction to be official and a binding contract for both the high bidder
*and* the seller.

This is just how I've always figured it. Frankly, I don't
think that "I've deceided not to sell" should be an allowed
reason for cancelling someone's bid. If you don't really
want to sell something, you shouldn't list it in the first
place. There have been two cases where my high bid has been
canceled for this reason and I'm very certain that in at
least one of those cases, it was because the seller wasn't
getting as much money as they wanted. ~_~

Anyhow. . . I'm going to go find something on-topic to reply
to now. ^_^
