ZBiddy is a scam - I have been onitoring this auction (I did sign-up and I bought a 'bid-package.
I NOticed that the same 'bidders' seem to be bidding on the auction running up the price - and eventually winning, over and over. They are obviously 'bots' - (roBOT bidders - not real people)- so the real people who bid, have no chance of wining. Unless it's for a $5 Chilis Gift card - big deal...
Total SCAM - don't waste your money!
