I"m with Neal on this one. I snipe and put my "max" bid in at the last minute. that stops the shills and also keeps people who decide to raise their max bid only after they get beat. Usually it is some fool who will "think" about it and not want to lose the bid so they go and ask their mom for a raise on their allowance or borrow more money from their grandma.
if you give these people more than 14 seconds to think about it they will always raise their bids. Why drive up a price if you don't have to?
Nowdays I don't use PayBay now that PayPay is required to play. Things might have changed in the 2 years or so since I've actually bought anything over at PayBay.
