Most sellers would be delighted at that news!
One reason Auctions are so little used on eBay (less than 15% of listings) is that buyers don't like them and don't bid, preferring Fixed Price or Buy It Now, not to mention Best Offer options.
Sellers are here to turn their stuff into cash. The more cash the better.
Auctions i used to be alone to bid or be only against one/two persons have 20-40 watchers now there's alway a few persons going into bidding wars plus a few sniping...
Watchers watch.
Many of them are either lookie-loos or competitors.
Bid.
But remember : Bid ONCE. Bid your MAXIMUM.
And bid late to avoid the nibblers. Or snipe, but not manually.
Many of those snipe bids were actually placed with an online bidding service like esnipe.com which will bid for you at the last possible second. There is a fee, although I believe there are often free trials.
