I've always been a bit of a sniper myself - just made things easier, since I don't have to sit and watch the auction feverishly the whole time. So it was with a bit of surprise to see someone actually come up with a service to do the work for you.
A quick glance shows that they appear to let you have 3 wins for free, then you pay a percentage of the price after that. Interesting concept. I wonder how it works if more than one sniper customer wants the same product - I would assume that the higher bidder wins, just like with a regular auction.
I wonder if they charge you a fee if you don't win. I'd imagine they couldn't, but I'm guessing that as the service grows, they need to pay for that growth somehow - the problem being what happens when you get multiple customers on the same auction - only one would end up paying you for the service.
