I have been on e-bay only since April or so, and as soon as I learn a bidder is another sister I stop bidding (exept in the case of a particular badge I really wanted, such as a sapphire one). I use the bidders past bids and e-mails to them to determine bidding patterns. Most of the bidders I have bid against, especially recently, are collectors. It's a shame IO cannot help.
Oh, and I'm "apd1806" on e-bay. It's my badge number at work.
