I feel that there are enough buyers to satisfy both auctions.
Well, if I was a consigner to the first auction, I would be mad as h**l that you have pulled this little trick and jumped in where you felt there was money to be made! This is an act of pure greed and doesn't even qualify as a business decision! If I was a consigner at your sale, I would truly be concerned about your decision making ability!
There is absolutely no possible way that this will benefit the collectibles community! The only beneficiaries will be those buyers lucky enough to have no competition on an item that can be resold for a substantial profit! But wait a minute----you've already stated that shill bidding is pretty much the same as a reserve???? I guess there really won't be any deals at all there any way, will there! Probably just a lot of NOSALE items that have to pay the commission anyway.
HHhhhmmmmm?????----yep--just greed.
