There are no automatic or bid increments on this auction. Unlike what happens on eBay, when you submit a bid the current price moves up to your bid immediately.  

We hope this prevents the last minute bidding action that is found on so many other sites. We are trying to host a reputable and transparent auction process that will give a realistic estimate of what that bottle may be worth. 

Once you bid, you are obligated to pay that amout (+shipping if required) if your bid wins.  There will be no excuses. Any non paying bidders will be kicked and banned from the site and all pages.
