Ok. I see you're new at this, so I'll try to explain how it works. You can also find an explanation if you look through the FAQ section. If an item is listed and I want it, and I bid 20 credits...it will show the bid as 1. Then you come along and bid 10. It will say you've been outbid, and then show the bid as 10. If you then bid 15, it will say the same thing, and then show the bid as 15. If you then bid, say, 21...THEN it will say you are the high bidder, and it will show the bid as 21.
You don't know what someone else has bid. They could have bid 100. You have no way of knowing, UNLESS your bid tops their bid...then it will show it.
No, there's no one sitting there outbidding you every second. If my lame explanation doesn't make any sense, then I do suggest you look at the FAQ.
