That is ridiculous. Bidding early just drives up the price for everyone else.
Peoples last minute bidding will then outbid your bid by a quid or so.
No, people don't go continually bidding in increments of £1. If you bid £100 and someone else bids £150, they'll win automatically win it for £101 when the auction ends. (although I think the margin increases with the item value.)
