louise, Hi, and Welcome.
First, thank you for coming to the forum and expressing your dislike, while leaving all the name calling and attitude behind... It's refreshing, and a different approach than most.
eBay IS a real auction, with real rules. We follow those rules. You can't fairly compare eBay to most live auctions. In live auctions you call out your bid and everyone bids as deep as their pockets are. With eBay your Max is kept secret, and a sniper only has one chance to bid. If you look at it that way, it's WE that have the disadvantage. Does that seem fair? If your items are selling for less than expected, I would suggest it's your early bidders that don't place a proper proxy bid. For some reason they would rather nibble their way up and stop as soon as they inch into the lead. Early, early bidders often get outbid. If the item gets to expensive, we pass and wait for the next. You never see our bid. That may be the other reason it seems we only get good deals.
If you check your records, you may realize snipers are among your best customers. They usually pay promptly, and are satisfied with a fair deal, even if it's fair, and not a steal.
