I too tend to bulk up a little toward Thursday in order to save on shipping ... pay a little more than I should sometimes? ... sure ... but to me, Over-bidding is the guy who pays FAR more than he should ... (such as $10 for an item I could buy at a store down the street for $6, or $68 for a box of cigars that could've been bought anytime for $59.95 on CI) ... I don't know whether they're unaware or just get caught up in a competition, seeking the "thrill of victory" ... I lose bids all the time to people who're willing to pay a little more than I am for a certain item at a certain time and win others on the same basis in reverse ... for the good of my CC, I just need to lose a few MORE ... lol
