Leonardauction

I was first to place bids on two items a few hours before the start of the auction. I couldn't "attend" the on-line, live auction, so I made two absentee $100 maximum bids on the items. When I checked later, I found that my bids did not win; rather, the items were sold to someone else for $100 each?! Apparently, no one bid higher than me, and I was first to bid, so why didn't I win? I will never deal with this on-line auction house again!
