Also if you are the highest bidder but have not met the seller's reserve; you can contact the seller as sometimes they will sell to the highest bidder or lower the reserve price.
If it was only a small difference, they may be prepared to accept the offer rather than chance relisting the item with more fees to pay, longer to wait and the chance that it might not reach the reserve again the second time, in short - that bid is evidently all they are going to get for their item.
