I find out the hard way that what you see on the item is not what you will get .
So the second time I bidder on a Lap top I did my research. I we to the computer shop with the items picture and all details I was to bid on and checked out all the good and bad things about it and how much cost of repairs ect.
No to the bidding CHECK the seller how long they have been on ebay and the response they have recived. Then find out were they are . DO NOT BUY FROM OVER SEAS stick to australia. If you can get the phone number of the seller . Ask questions and ask lots.
Check that you get some sort of cover on the item like 7 day money back or and 30 day warranty, Now you have the item , when you get it home check it and all the gear that came with it and if you can print the ebay description and check it with what you got .
PAY ONLY BUY PAYPAL.
Make sure you check postage and take out insurance . Ask the seller date when posted and get the Id postage number this is good for tracking.
I hope this helps .
