Basically these 2 sites are used in conjunction with eBay. What they do is you have to buy bid points, there about £5 for 500
Then all you do is enter the item number and it will AUTOMATICALLY bid on the item within about 3 seconds of the auction ending.
This means you win far more items because other people do not have time to bid after your bid is placed, and also you don't have to wait at the pc clicking refresh

You could even be asleep whilst it bids for you.
Just thought it would be handy for you guys to know.
