I've used Gixen, too, to great effect!
Anyway, sniping is a way of submitting your bid in the last moments of the auction.
It's useful in a number of ways
- you don't reveal your hand too early in the auction (my Uncle is a world renowned collector of some quite boutique pottery items and found that whenever he placed a bid on something it would signify to others that it was worth going for)
- you can bid even when the auction ends at an inconvenient time
- there is a CHANCE that people won't have time to place a bid after yours has been submitted
- you can submit your maximum and not get trigger happy at the last second when bidding manually, and pay over the odds for something
- you can submit a low bid for something you don't "need" and forget about it. Then if you win, you've got a bargain. If you don't, it doesn't matter
BUT
- you have to reveal your ebay id / password to the sniping service so they can submit your bid on your behalf (I've not had a problem, but it's worth changing your password frequently just to be safe)
- understand the way bidding works on ebay first. The highest bid you see is not necessarily the winner's maximum price. The items you lost out by 1 euro only went at that price because the auction winning price is the SECOND highest bid, plus the increment at that price. So if you bid £25 and had the second highest bid, it would sell at £26 but the winner's MAXIMUM bid might have been £40 so even if you had bid £38 you'd still have lost it.
Sniping's great. I use it a lot to set the price I'm prepared to pay for something then walk away. If I don't get it, I didn't want it badly enough.
Hope this makes sense!
