Hi, I have a question. Say I have the current bid of $240 on something. I put my max bid as $280. If the item is not wanted by anybody else, will Bidslammer automatically bid that $280 bid with 10 seconds left even if I am the winning bid without that $40 premium?

Hello Michael,
Thank you for your question about sniping an item you already won. The short answer is that we place the bid no matter what. If you were already the high bidder, eBay's proxy bidding system does not raise the price any more. However, if a bidder comes in between, the cost will increase up to the second-highest bid plus the bid increment.
