Hmmm....
Bid about £3 on a 99p top. Another bidder placed a couple of bids, outbid me and then withdrew the higher bid.
I had a quick peek at this bidder, and amazingly they have bid on 66 items, 100% of which are with the same seller. 36 bid retractions, and the only items won that I can see have been relisted immediately.
How I wish I could find a complete stranger (who isn't a friend or a relative or the seller with a different account at all, no sirree) who was so keen on my auctions that they bid on everything going and didn't even want it when they won!
