I have looked in to ebay this is a very proular site for buying cheap goods. They can ethier be new or second hand prouducts. It is set up as a acushen so that once a prouduct is posted you have a setait amount of time to bid it can be up to 9 days. Now they aslo have a buy now feacture which tell yoiu a price which they would be whiling to sel and you can bye it straight away. The lastest feacture thou is to be able to do best offer this is good for the celler becsause people have to say they maxuim what they would be whiling to pay the problem with this for the buyer though is you dont no what other people have bid.
