being primarily a live only auction we have very few problems like the ones you mentioned. Since we guarantee all our cards to grade and our autographs to pass returns are zero (if you take us up on the guarantee we submit for you). Honestly I've had a couple of difficult consignors who sign stuff over to me and then want to change their minds or their terms but that's by far the exception not the rule. Of course I would argue that my buyers likewise would have very few negative experiences with me.
I know I'm probably not the Scott you were referring to, but since N54 absentee bidding ends for my Tuesday auction tomorrow night I thought I'd get a plug in!
