Yeah, playfield got leveled because now everybody and their dog can use snipers (hey, where's the reward for technical competence?). So the "game" looks similar to before automation, but is more complicated. A positive feedback loop of increasing complexity if you like. For me, "the only winning move is not to play". </rant>
This doesn't make sense, really. You enter the price you're willing to pay in an auction; what everyone else bids is irrelevant to you.
If you are getting outbid, it's because someone is willing to spend more money on the item, bot or not. Don't bid low trying to get a deal. Bid what you are willing to pay, and it works every time. It's a very efficient system.
