somit i can help someone with he he, i aint no computer wizz kid but i use ebay
The best place to start with ebay is to register with them...you cant bid on anything your searching for unless you've registered so look at the top of the screen and click on register option in the small blue writing above the "buy" "sell" options.
Fill all your details in in it then you can bid away.
you can also register with paypal to assist you in buying because most sellers only accept that form of payment, you will be offered this option when you go on to buy a product. somewhere near the log in sign there will be a register option again. Its pretty quick to do these days too, you just fill it out and then wait around for an automated phonecall to check your identity.
Once registered with ebay, you will have your own spot called "my ebay" which will show on the top option bar. When you are searching for items you like and select one to see further detail, you will come across "watch this item" option. If you select that it will send it to your my ebay page and will automatically link a message to your e-mail account when there are only a few hours left, even if your not logged in! COOLUS MAXIMUS!!! he he You also use the my ebay to leave feedback for the sellers you buy from.
I personally place bids at the end of the sale when there are just a few minutes left, the maximum bid DOES NOT count as the amount that you are bidding for the item at that moment, its literally what you WOULD pay most if you had to. Once you type that it will add a penny (or whatever) over the sum the last bidder placed until it reaches your "maximum".
GOOD LUCK!
This is my first advice thing so i hope it helps BYE!!!
