I recently bid in a couple of auctions with proxibid. One of the auctios was fine, quick delivery, item was as desvribed. The second auction wasn't. I paid for the item and after 3 weeks it hadn't arrived. I called proxibid and the representative said to wait a couple of days and they would try to intervene. I called proxibid back a fes days later and cancelled the order (so I thought). Two days later the item arrived, I called proxibid to say that a 4 week delivery was unacceptable and I wanted to return the unopened package. I was informed the order wasn't cancelled and I had to work with the seller directly, amd proxibid had no authority to intervene on the buyers behalf. Not a reasonable policy, you may have good results, but you are at the mercy of the individual auction houses.
