Hi,
I have been a lucky guy so far... I have won almost every item I want via manual snisping. That's the reason that makes me wonder if I really want to sign with this service.
Anyway... You said that you received mails from underbidder... Well.. I have SENT mails to outbidder snipers that outbid my bookmark bid the within the last minute... I always wish them luck next time.
I always laught a lot when I imagine them reading the message "You're the Higher bidder" second before the closing time (with a satisfying smile in his/her face), and when they reload the view item page the noticed that I am the real winner.
Perhaps they use a service like this, perhaps dont... whatever... It's a kind of game between the snipers community and me.
Will
