Hi fish0699
Automatic bidding, in most cases, refers to eBay making the bids for you.
So, instead of you sitting in front of the computer bidding each time you're outbid, you just place one bid for the maximum amount you're willing to pay for the item.
Then if somebody bids, eBay's little proxy elf slaps down some of the money you've authorized, to keep you on top. He'll keep doing that if more people bid, until the authorized amount runs out or the listing ends.
What doesn't kill you, makes you stronger.
