Some bidders will step up the bid a bit at a time until it's just over the current high bidder's max. Placing a bid early can leave one open to that. Placing a bid for the same amount in the last few seconds avoids that and increases the chance of winning. Sniping software/services allow me to "place" my bid at the last second AND take my emotional attachment of the picture, protecting me from the dangers of last minutes bidding wars.
Yeah, but it's like investing. You gotta plan for the long run. Setting a price and sticking to it is better for the bank account, and it also works against the 'gotta win' ultracompetitive streak that auctions bring out in people. Or me, anyway. :ashamed001
With my schedule, I just snipe. I don't have time to mess around checking in on stuff day after day. I still get beat the vast majority of the time....however, I have sniped a couple of Wade & Butchers in the very recent past.
