You said “Bid was not high enough” but it was higher than the bid that won! Why didn Rovatron place my bid?
You have been bitten by the notorious “minimum increment” problem, in which the amount extra you bid wasn’t enough to win the bid because the increment between the two is higher than your extra amount. eBay has a table showing the minimum increments in US$ here. In detail: The minimum increment is the smallest amount you must add to the current winning bid to become the winner yourself. It ranges from $.05 to $100, depending on the bid amount. It increases as the bid price increases. You can discover what it is during the auction by looking down at the area where you’d enter the bid amount manually, or by referring to the chart above. Especially on larger-ticket items, it is often more than $1.
