It has pros and cons. I had pre bid on an item and when it came up Jaime said that he could'nt take it as low as I had bid, so I had the option of buying or not. Yesterday morning, I put another bid on the new lapis lazuli pendant, the same price it had gone for the previous day, as I was going to be out most of the afternoon, I had an e.mail saying that it could'nt be done, for what reason I don't know, I assumed they were perhaps all gone. When I logged on last night I had won it !!! They must still have a few glitches in the system, but all and all I think it is a better way.
They just need to work out a way of people requesting to see an item without being commited to buy.
