if there isn't a reserve price then there are probably like 6 days left meaning the price will go up to at least 100, but MAKE SURE YOU READ THE FULL ITEM DESCRIPTION
usually the prices rises the most during the last like 2 mins of the auction
when you win the item with the highest bid, you click 'pay now' and use paypal to send him the money. then he sends you the item. if he never sends the item, contact him and if that doesn't work then you have 45 days to file a claim with paypal
maybe you should ask your parents to do it for you after they give you your bath...........................oh snap
