That's it in a nutshell. Sniping program or not (ive used one in the past myself) it makes no dam difference.
What is dafter is the numpties that sit by the PC upto 4 days before the end of the auction, bidding, bidding, bidding, bidding again, getting into bidding wars whilst all the time they are inflating the price much to the joy of the seller and then moan when they get out bid!
Just bang in your absolute max a few secs from the end, you either get it or you don't.
And yeah, it is really that simple!
