출처 1: Bidding 101: A Tutorial for Beginning eBay Bidders (Michael Miller 지음. 2005년 11월)


※ 발췌 (excerpt):

( ... ... ) HOw does bidding work? In a nutshell, it's as simple as telling eBay how much you'd be willing to pay for an item--and then finding out whether anyone else is willing to pay more than you. If you've made the highest bid, you win the auction--and you have to buy them. It's important to remember that it doesn't cost you anything to bid. You only have to pay if you win--and even then, you don't have to pay any fees to eBay. (All eBay fees are charged to the seller.)  You'll have to pay the seller the amount of your winning bid, plus any necessary shipping and handling costs to get the item to you.

( ... ... ) Thanks to eBay's automated bidding software ( ... ), registered bids will only be as high as necessary to beat out the next-highest bidder. If you bid $40 but the next highest bidder bid only $20, you'll win the auction with a $20.50 bid.

( ... ... ) And you should $40 bid even if, at the time, the current bid is only $1. Now, you might think that if the bidding is at the $1 level, you should bit no more than $2 or so. This isn't the case, again thanks to eBay's automated bidding software. ( ... ... )


Understanding Proxy Bidding

The automated bidding software used by eBay is called ^proxy^ (or "robot") software. If you're a bidder, eBay's proxy software can save you time and help ensure that you get the items you want (if you're a seller, it doesn't really matter, because all you're interested in is the highest price at the end of the auction...)

On eBay, proxy software operates automatically as an ^agent^ that is authorized to act in your place--but with some predefined bidding parameters. ( ... ) The proxy software bids as little as possible to outbid new competition, up to the maximum bid you specified. ( ... ... )


출처 2: eBay Customer Service

You can leave feedback after you buy or sell an item. Buyers can leave a positive, negative, or neutral rating, and a short comment for sellers. Sellers can leave a positive rating and a short comment for buyers. ( ... ... )


출처 3: eBay Bans Negative Feedback For Buyers; Everyone Be Good Now (TechDirt, 2008년 2월 5일)

( ... ... ) Now, the company has banned sellers from giving "negative" feedback on buyers. This is quite an interesting move. Years back, eBay was often held up as the epitome of user feedback/rating systems. However, over the years, problems have cropped up, leading to questions about how effective the system really is, as it's often been gamed. A specific complaint is that many buyers are afraid to leave negative feedback, as a seller can retaliate and provide a similarly negative response to the buyers. The hope, then, is that by not allowing negative feedback, buyers can start being more honest about sellers. Of course, from the sellers' standpoint, it also means it's much more likely that buyers can now be problematic, without worrying about a response. eBay claims that it will now personally handle complaints from sellers about problem buyers
