I am not sure I understand your question. I logically would like you to bid high but you as the buyer would likely want to get the best deal. Listia understands this and your bid only increases when someone else bids higher than you. So even if you bid lets say 100, your bid will not increase until it is challenged. This happens automatically if you have bid higher than the necessary current bid. This is why if you have been bidding that it might not be registering, because someone might have bid higher than the current listed bid. Unfortunately, I can not change this auction and even If I could I do not have the ability yet to offer a buy now option.
