This guide should be useful to you if you are a first time bidder on Ebay.
SIMPLY... DO NOT BID UNTIL THE LAST MINUITE!!!
I find it very annoying when I am bidding on Ebay and there is a long time left on the listing, it started off as a 1p or 99p starting bid and the current bid is about 30.00. There is no point in doing this as you just push up the ending price, which is why if it starts low, keep your bids low until the last seconds!!!
I hope this information helps you
