Or in the bid retraction strategery ;) ....is if an item is at say 349...you put 1000 in and it raises the current bid a small amount above the previous high bid.
Then you retract that bid now knowing where the high bidder is at. Watch to see if no other bids are placed, and if there isn't, bid over (now knowing his top limit) by 10 bucks in the remaining moments .
It rarely works some unknown always comes in at the end and outbids everybody lol..
But you can check another's maximum bid..while the auction is in progress..lol
