My personal view is, that's life. If I want, I can play the game and use the software. Since I don't, I live with losing an auction here and there.

No I don't like getting sniped at the last seconds, but it's the same rules for everyone, so I don't have a real problem with it.

As a seller, you did make a good point. Sniping circumvents the natural bidding process and reduces the final sale price.

You wondered why some sellers us sniping software. Just remember that some of these people buy and re-sell items.
